Is there some way to write this simple regular expression more concisely? (here I am using separate lines to improve readability, even though I normally wouldn't use them)
(
(regex (matches|corresponds to) string)
|
(string (matches|corresponds to) regex)
)
"string" and "regex" are switched around here, and I want to express this concisely. I want to avoid writing (matches|corresponds to) more than once.
