I agree, as a rule, that we should trust the programmer over the compiler
with regard to the "inline" keyword.

However, that doesn't get around the fact that we have an -O3 switch,
enabling a mode where the compiler has to make decisions to inline
additional functions.

In such cases, the compiler cannot ignore the effect of constant arguments
causing much of the code in a called function to disappear when the called
function is inlined.
