It might be easier to implement (particularly for templates resolving to
functions) if we didn't reuse a keyword. Perhaps use __self:

template longNameWithSpecializations
{
    void __self(){...}
    void __self(int i){...}
}

The compiler can replace __self with the innermost template name. A nice side
effect might be anonymous lambda recursion:

a => a > 2 ? a * __self(a - 1) : a

I think lambdas are implemented as templates, so the above feature might work
naturally.

Eventually it would be nice if error messages used myTemplate.__self instead of
myTemplate.myTemplate.
