The list has two "1." headers.

Nice idea, I wonder if the compiler couldn't do this automatically with 
alias, however. It already does this in some cases (e.g. string instead 
of immutable(char)[]).

This would help solve the problem that error messages aren't going to 
get better when you pass it into something that only accepts the aliased 
type. However, for the most part, these are non-template functions anyway.
