In the string.Template documentation
(http://docs.python.org/library/string.html) it's explained that if a
custom regular expression for pattern substitution is needed, it's
possible to override idpattern class attribute (whose default value is
[_a-z][_a-z0-9]*).

However, if the custom pattern that is needed is just uppercase
letters, something like [A-Z]+ won't work because of the following line
in the _TemplateMetaclass class __init__ method:
cls.pattern = _re.compile(pattern, _re.IGNORECASE | _re.VERBOSE)

I would say that this is an error (IGNORECASE just shouldn't be there)
and that the line above should be:
cls.pattern = _re.compile(pattern, _re.VERBOSE)
and the default value for idpattern:
[_a-zA-Z][_a-zA-Z0-9]*

Do you agree on this? Is there any reason for the IGNORECASE option to
be passed to re.compile?
