I've heard that guessing about performance means nothing compared to

7 modules of 52 in qforeign are affected. It's hard to avoid: using
FFI is often enough to cause the problem. It's annoying that the
compiler can't figure out itself how it should compile things and I
must mark modules explicitly, and that what should be marked depends
on versions of compilers and options, so even if it works in some
environment it can break in another.
Is it possible to apply this setting to parts of a module (e.g. parts
using FFI)?. I mean that ghc would do it itself.
