Since there's no compiler currently supporting user-defined literals we don't
have plans to use that feature at the moment, although I've seen the idea
entertained internally.
That said, we are adding support for having QString and QByteArray use static
read-only data. This reduces the need for run-time initialization and memory
allocation giving you essentially "free" read-only QString.
Look at these commits in qtbase for more information:

Refactor QByteArray to allow for const data
