Request for enhancement: .sh.regex.available_character_class

What do you think about adding a  .sh.regex.available_character_class
array variable which contains the list of available wctype character
classes for the current locale? I know there is no API to get a list
from the OS but libast could probe well-known names and put only those
in the array for which wctype() turned a non-0 value.
