Is it safe to use void* for representing _both_ variables and functions?

I know in C++ this was a problem in the standard, because a function
pointer may not be the same size as a pointer to a variable, and
therefore dlsym technically has undefined behaviour (though I doubt if
any implementation actually doesn't work).

What's the situation in D? What if the library exports delegates? Would
it be dangerous to cast it to void*? Do we need separate functions for
loading function symbols vs. data symbols?
