Yes of course.
I do test name mangling but I was hoping for more "classifying" feature
with labels and was expecting a simple
OR and AND operation with labels. This is not the case.

It could have been nice but may be overkill my needs.
A repetable ANDing -L or -LE will do the job.

That said since test filtering is regex-based I simply rediscovered that
ANDing or negating regex is not easy.
