Hi everyone,
Sometimes I write grammar constructs like this:
StringLiteral: STRING_LITERAL
and use StringLiteral in subsequent rules, instead of STRING_LITERAL directly.
The reason is readability, and to stay consistent with an EBNF specification.
I wonder, does this cause a negative performance impact? When I compile the
parser with extra debug output I see that it actually performs a
STRING_LITERAL --> StringLiteral reduction.
Thanks in advance,
Frans
