To inline, the source must be known. The best way to do that is the way
std.algorithm does it - pass the delegate as an alias parameter to a
template.

What are the inlining rules for delegates/lazy arguments when the
delegate should be known at compile time? I'm porting some C++ code
with a number of #define's that give the first half of a for loop. The
body is naturally a delegate parameter, but performance is critical.

A couple other improvements to the inliner are possible:
1. inline functions with loops in them, as long as the place where
they are inlined is a statement rather than an expression
2. always inline private functions that are called exactly once, even
if they are large, if it is possible to inline them
