In practice, if you have a manageable number of regular expressions that use a limited subset or of regexp syntax, and/or a limited selection of strings that can be used to match against the container of regular expressions, you might be able to solve it.
Assuming you'... | 1 | 28 | 0 | I have a container of regular expressions. I'd like to analyze them to determine if it's possible to generate a string that matches more than 1 of them.
