I hope these aren't dumb questions:
Is there a quick & easy way to check if a module is pure-Perl, or is Perl+binary for both CPAN and core modules?
Do Perl+binary modules always use XS or are there other methods?
I need to code a function in C for the speed, is it possible to somehow include the C source in the perl source and get the C compiled? Or do I have to use XS and xsubpp?
I realise this is a bit like asking how long a piece of string is (*), but roughly how much faster will a C version of a perl sub be?
(*) it's twice as long as the distance from the middle to an end ;-)
I forgot to say I'm running ActivePerl on Windows
