r'...' disables escape sequences. This fixes validator errors:
/home/marek/dev/mesa/src/mapi/mapi_abi.py:45: SyntaxWarning: invalid escape sequence '\w'
'^(?P<type>[\w\s*]+?)(?P<name>\w+)(\[(?P<array>\d+)\])?$')
/home/marek/dev/mesa/src/mapi/glapi/gen/api_exec_init.py:43: SyntaxWarning: invalid escape sequence '\p'
