first work on the language (syntax and semantics) then on the presentation (pretty-print)

What do you think of what I propose?


1: Sentence body between keywords
::
...
;

=>

BLOCK
...
ENDBLOCK

3: Syntax as PN (prefix notation) only for declarations and definitions of vars, not IN (infix notation)


LOCAL { z a } { 0 1 }

LOCAL { a b c d e f g ... } 0 @ Assigns to all variables the value of 0

{ 0, 1 } { z, a } ->
In place of
0 1 -> z a @ IN (infix notation)

4: static vars

«
STATIC 'z' 0
STATIC 'a' 1
BLOCK
....
ENDBLOCK
