"convert" has no benchmarks of it own... because it does nothing. :-) It's a
"manager" class rather than a "worker" class. It's merely an interface to
coordinate/unify and uniformly deploy (or quickly swap on when-needed basis)
varying conversion facilities. So, with the "coerce"-based converter
"convert" performs as fast as "coerce". I actually ran tests with
lexical_cast and others: naked lex_cast vs. convert+lex_cast. No performance
degradation. I mention it in the docs.
