There is one exception... matching strings. There we have a powerful means of specifying patterns (regular expressions), and a multi-way branch based on the content of a string is a common situation. A new way to write this:
s = get_some_string_value() if s == '': continue; elif re.match('#.*$', s): handle_comment() elif s == 'DEFINE': handle_define() elif s == 'UNDEF': handle_undefine() elif re.match('[A-Za-z][A-Za-z0-9]*$', s): handle_identifier() else: syntax_error()
would be might be nice, but I can't figure out how to make it work more efficiently than the simple if-elif-else structure, nor an elegent syntax.
