I think there should be some way to force the compiler to inline 
a function. As a bonus, the error message can tell the programmer 
why the function could not be inlined, allowing them to make the 
necessary adjustments.

Different compilers will have different inlining capabilities, 
however at the point where programmers are forcing inlining on or 
off, they are already micro-optimizing at a level which implies 
dependency on particular compiler implementations.
