The CLASS_* names come from the Fortran standard (where the term 
"impure" is a F2008 addition). Well, looking at the standard you find:

13.7.10 ALL (MASK [, DIM])
Class. Transformational function.

The procedures "OR" and "XOR" are GNU extensions; the manual does not 
tell which kind of functions they are, but the standard Fortran "IOR" 
and "IEOR", which are the Fortran-standard replacements, are "elemental 
functions". If one changes OR and XOR to elemental, one also needs to 
update the documentation, cf. 
http://gcc.gnu.org/onlinedocs/gfortran/OR.html and 
http://gcc.gnu.org/onlinedocs/gfortran/XOR.html
