Sounds good in principle.  So, if I understand right, a pragma(inline, true) 
anywhere inside a function adds a compiler hint to always inline this function, 
while with false it's a hint to _never_ do so, and no pragma at all gives the 
usual compiler-decides situation?

Question: what happens if someone is daft enough to put both true and false 
inside the same function?

In any case, could you possibly provide a slightly more detailed code example 
with accompanying explanation of what the intended results are?
