[pypy-dev] JITability

[Serhat Sevki Dincer]

Hi,
Suppose you have a function to validate local/international phone numbers
(one space between number groups, no space at start/end, no zero at start)
like:

def validatePhone(v):
   if not (9 < len(v) < 19 and '0' < v[0]): *# recall ' ' < '0'*
       return False

   for c in v:
       if '0' <= c <= '9':
           wasspace = False
       else:
           if c != ' ' or wasspace:
               return False
           wasspace = True

   if wasspace:
       return False # last one
   return True

Just out of curiosity, would JITability of this function change if I put
"wasspace = False" just before the loop ?

Note: attaching just in case indentation is lost when sending..
