I need re.match when parsing the whole string. In that case I never
want to search through the string, but process the whole string with
some regulat expression, for example when tokenizing. For example:
pos = 0
while pos != len(s):
match = TOKEN_RE.match(s, pos)
if match:
process_token(match)
pos = match.end()
else:
raise ParseError('invalid syntax at position %d' % pos)
