misleading name for two-parameter Foam::name()
currently accepts a printf-style format string. It should probably be renamed as
formatinstead. Since this is reasonably infrequently used, I think that it should be relegated to the stringOps namespace as well. Eg,
In fact, probably want to make the whole thing templated:
template<class Primitive, class StringType=string> StringType format(const char* fmt, const Primitive& val)
If desired, could have convenience static
word::format as part of the word class, etc.
Might also consider with Args... forwarding.
