I actually answered only the part about 'static' being useless. Sorry
for not being clear on that.

That is indeed true.

Not at all.

> If you are not questioning that. Are you ok with me using prototypes?

I do prefer to organize tests so that we don't have to use them, but I
can live with code that does not follow that as well.

For modern enough compilers and debuggers this is not true. Ancient
tooling may loose some debugging information when functions are inlined
though.
