The code that you're referring to there doesn't just generate ops and pad entries, it also parses general Perl code, in which (for example) "shift" could mean all sorts of things. Using lex_stuff, your implementation is liable to be broken by local redefinition of a keyword that doesn't appear in the user's source. That's OK for a prototype, but not at all OK for a serious language feature. -zeframThread Previous | Thread Next
