I also researched something similar about 1 year ago and concluded
that it is not possible (but I think CHAOS supports a string-type
preprocessor data structure which I did not investigate because it is
not available for all compilers).
This can be done instead if you are willing to wrap the single
characters between parenthesis:
STRING_TO_TYPE( (M)(y)(T)(y)(p)(e) )
If this would work for your application, I can post the code for this
macro (or just look at BOOST_PP_SEQ_FOLD_LEFT() or similar and program
it yourself). Let me know.
