In my opinion it should be illegal to implicitly convert from one calling
convention to another.
The case where either calling convention will produce the same code could still
be allowed, but I doubt there will be much (if any) use for it.

import std.stdio;

extern(C) void foo(real r)
{
	writeln("foo");
}
extern(D) void bar(real r)
{
	writeln("bar");
}

void main()
{
	auto ptr = &foo;
	ptr(0.L);
	ptr = &bar;
	ptr(0.L);
}
