I added and alternate syntax for blocks of instructions.
...
The syntax: block { ... }
The other syntax: begin ... end
This implies adding a new keyword to LIGO: "block".

...
Syntax: if ... then ...; else ...

I added set definitions by extension.
...
For example:
const bar : set (int) = set 1; 1+1; f(3); end

I extended the right-hand side of assignments to accept "None"
...
without type annotation.
This is meant to enable specify the removal of a map binding.
Note: The index assignments in loops are not concerned.

I extended left-hand sides of assignments to have qualified paths.
...
Note: In loops over integers, the initial assignment has still a
variable (the index) as left-hand side.
A qualified path is of the form "x" or "x.y.z" or "x.y.z[t]".

I added qualified names (paths) as left-hand sides of assignments.
...
For example:
store.funded := True;

Ported to constant declaration the work done for variable declarations.
...
That is to say, now constants can include unannotated empty lists etc.

Added qualified names to patches ("patch x.y.z with ...").
...
Fixed grammar for map patches (should start with "patch", not "map").

Replaced expression "copy ... with ..." by instruction "patch ... with".

I relaxed the extension to the grammar that enabled non-annotated
...
empty lists and None values as initial values in declarations.
Now, these values are accepted irrespective of the declared type. It
is up to the typechecker to validate them.

I relaxed the grammar to support in the parser for initial values of
...
variables to not require type annotation, like
var x : list (operation) := []

Changed "do nothing" to "skip".

Removed keyword "null", replaced by two keywords "do"
...
and "nothing".
Until now only products of type names were allowed: I extended
them to allow type expressions.
Removed the destructive update of a map binding "a[b] := c".
Record projection has been extended to allow for qualified
names: "a.b.c" and "a.b.c[d]".
Changed the LIGO extension from ".li" to ".ligo".
Fixed the name of the language to be "LIGO" (instead of "Ligo").

Added keyword "storage" as parameter kind (with "var" and "const") for
...
entrypoints.

former and return the latter.

I added record creation (injection), field selection (projection)
...
and functional update (copy).
The only creative piece of concrete syntax is that of the
expression for functional updates:
copy foo with record field = value end
where "copy", "with", "record" and "end" are keywords.

Declarations can now be written in any order. Removed top-level block.
...
The parser exports now an entry rule for parsing Ligo expressions.

Storage and operations are now explicitly named.
...
Refactoring of AST to enable the detection of incomplete pattern
matchings by the OCaml compiler. Some record fields renamed for
better readability.
