Agreed.

This is not true.  Granted, it's relative to the user, but realize that
programmers that consider that + is concatenation have a distorted view.
+ is addition for everybody. The concatenation operator is always
denoted with some something else (ยท or ! or empty, etc).

But foremost, in the case of C:

1- string + integer and integer + string already has a meaning so you
   cannot use + to mean concatenation in those cases.

2- string-literal string-literal already means concatenation.  So it
   would be much better to use empty for concatenation, than +.
   (But ! would be even better, and as binary operator it's free).

Nope.  Again, using arithmetic operators to work on string is a bad
idea. Do you remove it as prefix? as suffix? in the middle of the
string? Do you remove multiple occurences?

Also, you should not consider just strings.  Strings are vectors of
bytes.  There are other vectors of integers in C.  And what about other
vectors? (eg vectors of structures, vectors of pointers, etc)

This is just a string processing library.
