EXAMPLE: 1.0|1.4* matches 1.0, 1.4 and 1.4.1b2, but not 1.2. – < Returns a generator of unique elements in the sequence logic The basic idea to nest logical expressions is instead of trying to denest things via distribution, we add new variables. So if we have some boolean constants True or False; that is, it is the callers' responsibility to do the conversion of expressions recursively. This is done because we do not have data structures representing the various logical
