Set membership is now a full-fledged expression.
...
It used to be tied to the test expression of a conditional.

Support for empty sets and maps. Alternate syntax for maps and lists:
...
sets, maps and lists are now homogeneous.
Lists by extension now require the "list" keyword, like sets and
maps. Semicolons needed, instead of commas.
New syntax for lists: `list [e_1; e_2; ...; e_n]`.
The empty list can now be denoted either by `list []` or `list end` or
`nil'.
Both `list` and `nil` are new keywords. Lists can also be denoted
without brackets, as sets and maps: `list e_1; e_2; ...; e_n end`.
The extension for maps follows the extension for sets: `map [b_1; b_2;
...; b_n]` or `maps b_1; ...; b_n end`.

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".

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]".
2019-03-20 14:59:10 +01:00

I added qualified names (paths) as left-hand sides of assignments.

disabled by mistake in the last commit).

Maps can be defined by extension in declarations.
...
"map" has become a keyword to introduce definition of maps by extension in declarations ("map" ... "end"). This entails that a grammar rule had to be created to handle the type expressions "map (..., ...)". Concordantly, I added map patches, modelled after record patches.
I created a node in the AST for map expressions (currently only
map look-ups).
I refactored the parser with parametric rules.

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").

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.
