…operations (#227) In view of the plan to develop a self-contained automata theory in cslib, the patch restores the closure properties of regular languages under boolean operations that were removed in #209. Note that in order to avoid conflicts with the equivalent theorems in mathlib, the `_cslib` suffix is added to theorem names.
