Having an ergonomic product is crucial on multiple levels:
Making features easily accessible ensures they’ll actually get used.
Not wasting users time on idiosyncrasies frees more time for making contracts safer or building apps.
Keeping users in a Flow state makes it possible to introduce more complex features in the language.

### The Language
LIGO should contain as few surprises as possible. This is usually known as the principle of least surprise.
Most programmers who will use LIGO have already spent a lot of time learning to develop in an existing language, with its own set of conventions and expectations. These expectations are often the most important to accommodate. This is why C-style syntaxes are especially popular (e.g. JavaScript), C-style is well known and new languages want to take advantage of that familiarity. Therefore as an extension of the principle of least surprise, LIGO supports more than one syntax. The least surprising language for a new developer is the one that they have already learned how to use. It’s probably not practical to replicate the syntax of every programming language, so LIGO takes the approach of replicating the structure used by languages from a particular paradigm.

### Editor Support
Without editor support, a lot of manipulations are very cumbersome. Checking for errors, testing, examining code, refactoring code, etc. This is why there is ongoing work on editor support, starting with highlighting and code-folding.
### Docs
Docs include documentation of the languages, tutorials, as well as examples and design patterns.
We’re a long way from there. But having extensive docs is part of our goals.

We are performing the following steps:
1) Simplifying the for body using ̀simpl_block`
2) Detect the free variables and build a list of their names
(myint and myst in the previous example)
Free variables are simply variables being assigned but not defined
locally.
Note: In the case of a nested loops, assignements to a compiler
generated value (#COMPILER#acc) correspond to variables
that were already renamed in the inner loop.
e.g :
```
#COMPILER#acc.myint := #COMPILER#acc.myint + #COMPILER#elt_x ;
#COMPILER#acc.myst := #COMPILER#acc.myst ^ "to" ;
```
They must not be considered as free variables
3) Build the initial record (later passed as 2nd argument of
`MAP/SET/LIST_FOLD`) capturing the environment using the
free variables list of (2)
4) In the filtered body of (1), replace occurences:
- free variable of name X as rhs ==> accessor `#COMPILER#acc.X`
- free variable of name X as lhs ==> accessor `#COMPILER#acc.X`
And, in the case of a map:
- references to the iterated key ==> variable `#COMPILER#elt_K`
- references to the iterated value ==> variable `#COMPILER#elt_V`
in the case of a set/list:
- references to the iterated value ==> variable `#COMPILER#elt_X`
Note: In the case of an inner loop capturing variable from an outer loop
the free variable name can be `#COMPILER#acc.Y` and because we do not
capture the accumulator record in the inner loop, we do not want to
generate `#COMPILER#acc.#COMPILER#acc.Y` but `#COMPILER#acc.Y`
5) Append the return value to the body
6) Prepend the declaration of the lambda arguments to the body which
is a serie of `let .. in`'s
Note that the parameter of the lambda ̀arguments` is a tree of
tuple holding:
* In the case of `list` or ̀set`:
( folding record , current list/set element ) as
( #COMPILER#acc , #COMPILER#elt_X )
* In the case of `map`:
( folding record , current map key , current map value ) as
( #COMPILER#acc , #COMPILER#elt_K , #COMPILER#elt_V )
Note: X , K and V above have to be replaced with their given name
7) Build the lambda using the final body of (6)
8) Build a sequence of assignments for all the captured variables
to their new value, namely an access to the folded record
(#COMPILER#folded_record)
9) Attach the sequence of 8 to the ̀let .. in` declaration
of #COMPILER#folded_record
