I tried to use __traits(compiles) but it always returns false for the

Hm.. that seems annoying. I'd guess you'd get simple tests to work,
maybe it's the way you are using __traits(compiles).
If all else fails, back out to the place where you are using it. At some
point, it is a function call. Just wrap that call, and check if it
compiles or not.
e.g.:
static assert(__traits(compiles, theFunction(theItem), "this code won't
compile: " ~ theItem.source);
// if we get here, it will compile
theFunction(theItem);
D can be quite perplexing when you have so much meta in it :)
