[Haskell-cafe] StableFunPtr?

Hi,

I've seen that if I'm going to leave a pointer
to data in the hands of foreign code, I should
use StablePtr so that the value it points to
doesn't change.

However, we also usually give FunPtr to foreign
code, like when registering callbacks, but I
can't found any kind of "StableFunPtr".

Are all FunPtrs stable?

Thanks,
Maurício
