Perhaps it's a little off topic, but...

Wouldn't it be better if the language was made so that evaluating an 
array as a bool would yeild false when empty and true when not? This 
would avoid forcing the !empty double negation at many places like this 
one.

	while (range) range.popFront;

instead of

	while (!range.empty) range.popFront;

and

	for (auto copy = range[]; copy; copy.popFront)

instead of

	for (auto copy = range[]; !copy.empty; copy.popFront)
