Re^8: XS: use module into package

I'm just trying to replicate use as it is internally for perl, so I can make it work with things like use feature 'say', which don't work with an eval qq{package $callerpkg; use feature 'say'}, but do if I use a goto &feature::import.

Nothing against eval, I just think that the behaviour is inconsistent for lexical "uses".

I'm just trying to replicate `use` as it is internally for perl `use` is a compiler directive to immediately do a `require` and (possibly) `import`. To replicate that, your code would need to be parsing Perl code. Your statement makes no sense. but do if I use a goto &feature::import. «`goto &feature::import`» has no resemblance to «`eval 'package Package; use Module;'`» and has nothing to do with «`use`»!!! This is getting silly. You have yet to communicate what problem you are trying to solve. When you figure it out, you should start a new thread. Nothing against `eval`, I just think that the behaviour is inconsistent for lexical "uses". What do you think `use` does with the code it loads? It evals it.	[reply] [d/l] [select]
