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.

Christian Rinderknecht

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]".

For example:

Extended map expression to map constants by extension.

disabled by mistake in the last commit).

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").

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.

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.

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.
