| Why? Could you plese provide rationale for this.

Because it is shorter and if the code is trim_copyto(s) is reads as though the
'to' means it goes to s.

(Of course, a rational language would specify in, out, or in&out but I won't
stir that hornets nest again!)

But actually I really rather like Rob Stewart's trimmed' suggestion.


   std::string t(trimmed(s));

or even if t already exists (poor but what novice and ex-C programmers may do)

        t = trimmed(s)

seems to me to imply that nothing is done to s.

But to_uppered(s) or uppered is not so nice, but still just OK?

And what about concatentation t += trimmed(s);

and addition string full_name = trimmed(forename) + substr( trimmed(surname); ?

Since we already have protection against misuse,
this seems quite attractive to me.
