Well, first we need an option to turn on the GC in dmd... ;-) Otherwise
we'll run out of memory as soon as std.algorithm is involved. :-P

Frankly, I think dmd should enable its GC when compiling for -release;
it's the release build, you aren't expecting a fast code-compile-test
cycle anymore, and you probably want maximum optimization, so why not
take the time to conserve memory that can be used for other things, like
whole-program optimization, or a longer but more powerful optimization
pass?
