No high-level language "gives a programmer what they want." Which is one
reason some of us still use assembler languages from time to time.
Any compiler worth its weight in bits will translate written code based
on analysis; I vigorously support intelligent compilation. What I do
*not* support is trying to be smarter than the programmer. A fine line
line, to be sure, but a line nonetheless.
If I explicitly define a variable type or a structure packing, I expect
the compiler to honor my wishes; if I say "inline", I mean "inline",
within the physical limits of the compiler (i.e., memory use during
compilation, etc.)
At the very least, a compiler should report when it has made a choice
counter to the programmer's wishes. If I declare a function inline, and
the compiler decides otherwise, it should inform me of its rebellion.
Perhaps I'll even agree with it -- but I want to know when my tools make
choices for me. I am writing the program, not the compiler.
