Nice! Will try it out.
Have you tried it on windows already? That's where we pay by far the biggest
price due to all the unnecessary process creations...
It looks like strawberry perl has FFI::Platypus, but not FFI::C. There is
perl/vendor/lib/FFI/Platypus/Lang/C.pm, but that just seems like it's
documentation. There is however FFI::Platypus::Record, which maybe could
suffice?
Do we actually need FFI::C, or can we work around not having it? Looks like
it's just used for notify related stuff.
It looks like mingw doesn't have packages for FFI::Platypus, but it'll
probably be a lot easier to build that than when using msvc.
