Re^4: Callstack manipulation?

Hi plobsing,

thanks a lot for your help! : )

I should mention that Moritz already implemented gather&take using coro http://search.cpan.org/~moritz/Perl6-GatherTake/ ...but he doesn't give the impression to be very convinced about the outcome.

Nevertheless I just wanted to give a motivation for a more fundamental question:

Are there any opcodes allowing to manipulate the call stack?

Popping and pushing the stack gives an approach to a whole bunch of Assembler techniques (and pitfalls of course ;)

Ok, at least one can manipulate the stack with XS, I found some examples in Advanced Perl Programming, describing macros to do so! 8 ) (over 10 years old but still an interesting read ) UPDATES: Concerning coro: AFAIS the coroutines get separated lexical variable spaces, complicating a Gather/Take-Algorithm to access "surrounding" variables. I was talking about the first edition!	[reply]
