I would expect that something could be written to turn a signature
string into a mangling and also provide the correct type upon return.
Something like:
auto f = getFunction!(@safe void function(int))("package.module.symbol");
and have it properly mangle the expected function name and pull it
from the dynamic library.

This would still have to be @trusted, of course, since there's no
telling what's actually inside the object file.
Of course it has to be trusted. The underlying function uses void *.
But not because you can't trust the mangling.
But this sort of facility totally should be in Phobos, or at least in
some dub package somewhere. It will make working with dynamically
loaded libraries in D so much more convenient.
I'm not really motivated to make such a package, as I don't do any
software with runtime loading of libraries. But I bet it would be either
accepted into Phobos and/or wouldn't be that hard to add for a library.
