Sorry for talking to myself, but I'm hoping someone will help
me out. The above idea doesn't work. It appears that only the
main program file is going to have function pointers while
modules and classes will have delegates. So, does a library
that uses callbacks need 2 callback register functions as well
as parallel storage mechanisms, or is there a fairly simple way
to make it polymorphic? I was hoping a newbie would be able to
use this library, but not many newbies are going to understand
this. I suppose I could tell them to call registerFunction and
if they get a compiler error, then call registerDelegate? Or
am I missing something?
I don't fully understand what you're doing, but functions can
easily be turned into delegates using std.functional.toDelegate
[1]:
import std.functional : toDelegate;
registerDelegate((&topLevelFunction).toDelegate);
