Nope. At best, you might be able to *declare* a function that is
GC, but even then, you wouldn't be able to call it.

Actually, you can "undo" @safe with an explicit @system. nothrow
(and pure) are in the same boat as @nogc

Solutions I can see would be to:
a) Put your unittests in a separate module.
b) Place your unittests before your "@nogc:"
c) Instead of using "@nogc:", use "@nogc {}": This will make
@nogc run until the end of the block.
