Only if you're a compiler implementer, or if you have to tweak compiler
settings, but even then trial and error is the best approach.
Double guessing the impact of inlining is one of the more futile pastimes
that could occupy one's mind, IMO.

I agree with Terje that the ideal time for the system to inline isn't
*necessarily* the latest possible.
