Yeah, I've recently started building the habit of always using
parentheses with const applied to a type, in order to make it less
confusing with const as applied to a function. Even though it's legal to
write:

	int func(const T t) {...}

nowadays I prefer to write:

	int func(const(T) t) {...}

so that when you need to return const, the syntax is more consistent:

	const(T) func(const(T) t) {...}

and it doesn't visually clash so much with const as applied to the
function itself:

	const(T) func(const(T) t) const {...}

This is one of the warts in D syntax that I find annoying.
