You don't specify the types of the parameters of the function

Yeah, I see that now. The compiler does have all the necessary
information to infer the argument types in both templates,
though. There's no reason that it /couldn't/ infer the type of
the argument.
yes, you can find alot of situations where it is theoretically
possible to infer types (sometimes by doing several passes to
"refine" the info), but dmd currently doesn't do that. partially
because it's a good amount of work, partially because it will
slow down the compiler considerably in some cases.
