There are two reasons.
1. I would like to avoid the efforts for development of a representative
test case for such a speed comparison.
2. I am using regular expressions in constraints (for my other source
code analysis)
because of functionality that is not directly provided by the semantic
patch language so far.
Can it be that the regex syntax is more succinct for specific use cases?
Regards,
Markus
