I wasn't aware that pragma(mangle, ..) can practically name any function

there's only a symbol name there's nothing I can do in my loader to
verify that a function is or does what it claim to be/do.
But that's the same as the linker anyway. It's possible to stub the
function as @safe, but implement it as @system and just pragma(mangle)
the thing. Therefore the compiler is no safer.
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.
