in reply to Re^3: How does perl's lexer and parser cooperate?
in thread How does perl's lexer and parser cooperate?
Got it, thanks again!
But I've got another doubt, what's the difference between ival&i_tkval, pval&p_tkval in YYSTYPE?
updateI've just checked other symbols like GRAMBLOCK,
it should be parsed by Perl_parse_block in toke.c, which is called as parse_block ,
but the strange thing is : they're never ever called from anywhere.
so when will yyparse got token GRAMBLOCK from yylex ?
