Or, in this case, fix the compiler to be able to inline delegates. Or is
there any other advantage of using an alias parameter instead of a
delegate?
1. It is likely to result in faster code when inlining fails. Eg. it
will often not allocate when the delegate would, due to nested template
instantiation simplifying escape analysis.
2. IFTI limitations. Eg. the following cannot work with the current
language unless 'map' is specialized to ranges of int:
[1,2,3].map(x=>2*x)
