Talking today, if someone said 'doesn't inline function work well?'
[assuming it works well] i'd say 'well yeah, inline function is great'.

I think people learned how to do stuff with macros [that is, if you
aren't adept at reading/writing macros, you don't really know C], then
they learned that inline function is available everywhere.

"If the macros work well, why do we want inline function, we will stick
with the stuff we are used to."

I wonder if this will change over time, where more people can't think of
a day when inline functions are not universal.  Maybe a bit, but i don't
think it's going to a world where almost everyone doesn't use macros and
doesn't really understand them.

I think this is a feature that C inherited from C++.  It seems to me,
once C++ had inline function and it worked, then everyone in C world
said 'well yeah, let's put that in'.  Oh and, Stroustrup said his goal
is to reduce use of the preprocessor.
