Skimming these:

I suppose doing s/POSIX/TCL/g (limited to regular expression usage
obviously) would be an acceptable change.

Adding "Advanced" in appropriate places would be good too.

I suppose I took it as face value that we were POSIX compliant rather than
just POSIX ERE compatible. It sounds like that was a false premise,
though, and that our use of POSIX, for those people for whom its not just a
noise word, implies a set of acceptable behaviors that we far exceed.
Calling it TCL is more accurate and allows people to easily tie back our
implementation to external resources like the first one above.
