Sorta hard for me to anticipate the future ;-) Anyway, I assume rng can be an
std::string as well?

I have no idea what this code does? Construct a range from chars that have
been upper-cased and write it into dst. Then copy the rng to while converting
it to upper, then lower, then upper? This one isn't winning me over with code

In the zero/one argument case there's no significant advantage. So I'll
repeat this case again:
//The next line makes me go read the docs again, every time
replace_all(s1,s2,s3); //which string is modified exactly?
s1.replace_all(s2, s3); //obvious which string is modified here
Of course, you want to be able to work consistently so you have to pull along
the functions with less arguments too.
