/* DEV_NOTE: this file is not intended to be used directly by any user code!
i.e. do not #include <omni/xxx_impl.hxx> and do not compile this source directly.
this file is included directly in other source.
The logic is that omni::cstring and omni::wstring namespaces segregate the types
for explicit calling; i.e. you can call omni::cstring::X to check on a std:string
and similarly can call omni::wstring::X to check a std::wstring, while still having access
to the OMNI_STRING_T_FW and omn::string::X functions (which are aliases for the other namespaces).
Since omni::wstring and omni::cstring are merely wrappers for the omni::string::util functions
(which are templated) that then pass in the appropriate types (std::string/wstring char/wchar_t)
putting the relevant code in a header with a few #defs for types makes keeping the files
in sync (for functions) less messy. It does introduce slight confusion to anyone who might
want to read this specific code or documentation though, hence this note.
