in reply to Re^2: Refactoring Perl5 with XS++
in thread Refactoring Perl5 with XS++

I think a pertinent question, then, is replace XS how? In one sense, XS is easily replaced if one has a powerful enough foreign function interface (FFI). In another sense, syntax that allows (possibly inlined) C to be separately compiled and to call back into Perl easily is required. If one wants to fully replace XS, the language has to be able to do both or do equivalent things to both.
