In the documentation, the grammar for Declarator is:

Declarator:
        BasicType2 Declarator DeclaratorSuffixesopt
        BasicType2 Identifier DeclaratorSuffixesopt

How is possible to parse something like " int i,j; "?
What are the parser reduction steps?

Thanks in advance!

Why not take a peek at the source :p? parse.c has the method parseDeclarator. Like any recursive descent parser, it just checks the next token and then chooses what to parse next. You have to kind of unwind the grammar a bit to get all possible tokens that can appear next.

The  only real definition for the D grammar is the parser code itself (cpp source code). The BNF in the docs is known to be incomplete and/or wrong. In the past Walter has edited it from corrections people has submitted so...
