errrm, no, it isn't - quite to the contrary: comparison functions which
have explict qlatin1string overrides are faster than with implicit
qstring::fromascii construction. same for qchar. and the "wrapper class"
itself is optimized away in release builds, so it doesn't add overhead.

the one gripe i have with the QLatin1* classes is the verbosity of the
code. this makes aliases like QL1S() pretty common.
