Sounds useful. For the Fortran side, I think it makes sense to wait 
until the C/C++ side has been solved. (See thread labelled "Extend the 
simd function attribute".)

However, I just noted:

This explicitly requires that the string is quoted using single quotes 
(') and not double quotes ("). I think that's acceptable for this 
special-purpose use, but, normally, Fortran permits both characters as 
string/character delimiter.
