said it's more efficient to put often-used and short functions as inline, so
they are taken care of at compile time, to save function calls overhead and
improve performance thereafter. this I understand, but how do u define "short
functions"?? dozens of lines or a
few hundred lines? or some big functions, I can divide them into smaller
funcs and make them inline?? besides, what bad impact if I make some large
funcs inline?

1. do customers care about compile time?
2. i am working on a server with 32G RAM, size doesn't matter.
3. large functions won't be used very often, otherwise they should be
divided into smaller pieces...

mutator
could
time

If there are some common parts within many functions, why didn't make them
a separate function in the first place?

funcs

similarly, many things can be made a function. for example,
a large func goes through a small block A, and another small block b is used
by some other funcs. a and b share about 60% logic, r u gonna make a function
including both case a and b or not? u know, even totally different logic can
be in one function as well, just use a if/switch branch...

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~faint, I mean some common parts within all funcs
of course.
case,
