Legally poisonous the BSD copyright I understand are way flexible to
commercialize compared to like POSIX classes. And technically the
regex parts I either don't fully understand or are "inconsistent"
relative logical complement, where a stronger logic criterion not only
consistent, more physical approach any value has physical
interpretation for applicables such NP, halting, and onwards. In
short, usable info whether regex POSIX part is "consistent" or exactly
what we mean when we say POSIX regex defined in terms of "complience"
or "compatibility" when using a regex complement implies infinity.
Thank you
