I think it's a problem with the precedence of the binary ! operator. It
has higher precedence than '.', so GetMembers!std.stdio gets parsed as
(GetMembers!std).stdio. Anyway, I've learned that if the argument after
'!' is more than a single token, you should just parenthesize the whole
thing, to be on the safe side.
