The ability to invoke blocks doesn’t really commit you to using clang (-base
has support code to invoke blocks when compiled with GCC) you only need it when
you want to create blocks (does CFRunLoop need to do that? I think it might
not…). So the question is rather whether we could rely on a compatible
libBlocksRuntime being reasonably widespread (libdispatch usually isn’t the
issue, but you need the version libBlocksRuntime that exports is symbols weakly
so that libobjc2 can override them). In other words: I don’t think
backwards-compatibility is as important for corebase as it is for -base.
I have one comment about the
‘weakly-load-NSCFRunLoop-if-corebase-is-also-linked’ thing: I think it’s a good
idea in general, but how would we handle cases where you start up without
corebase, and during runtime you load a bundle that is linked against it? That
might be a bit tricky to get right…
Cheers,
Niels
PS: Thanks a lot for working on corebase! I especially like having the CFStream
stuff available...
