We have list of terms which is begin and end with term and separate by delimiter, for example
ident , ident, ident, ident
statement ; statement ; statement ; statement
In ANTLR grammar we must write:
ident (',' ident)*
statement (';' statement)*
How simplify it? One proposal is:
ident || ','
statement || ';'
ident , ident, ident, ident
statement ; statement ; statement ; statement
In ANTLR grammar we must write:
ident (',' ident)*
statement (';' statement)*

ident || ','
statement || ';'

Andrezj,
It is very easy to build an ANTLR parser for whatever variation of ANTLR or EBNF grammar description languages you want. It helps that grammar description languages are very small (although ANTLR's is a bit large).
