Another method:
debug
assert(condition, format(string, arg, arg));
else
assert(condition, string);
because @nogc is ignored in debug conditionals, just like
purity is ignored in debug conditionals.
That doesn't cut it on so many levels...
First of all, no four lines solution that requires copy/paste
(or worse, retyping) as a standard will actually get employed
by programmers. The disincentive is too high.
This pattern is incredibly easy to wrap and reuse as needed. I
would've done already if only I'd known @nogc was ignored as well
as pure.
