> You want to use a regexp.

This view depends on some factors.
I would prefer to search for string literals (and their exclusion) by higher level means.


> I'm asking you to put the regexp in a python function.

How do you think about to improve the following software situation
besides the application of regular expressions?

@initialize:python@
@@
import re

@display@
identifier i =~ "^(?:[A-Z]+_){3,3}[A-Z]+";
expression e : script:python() { re.match('"', e) };
@@
*#define i e
