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.

    Quite so! And that's pretty much where I'm at: "in what sense would XS be 'replaced'"? And of course it's probably more like robustifying the API so that XS is directly used less often, or never if possible.

    Note that I'm not assuming any of this is likely or easily doable. Hard things are possible, though.
