There was this thing called IVORY which IIRC 'purified' TECO code so that it
could be dumped out in a compressed form (for faster loading, execution, etc
- it may have also been possible to have it read-only, and the page(s) shared
between multiple EMACS instances, but my memory is foggy on this), and Gene
did that.
There was a TECO compresser TECO macro, but that is a more limited beast: it simply would
compress out any spaces between commands, and convert string delimiters to their short
form. This definitely did make them smaller and slightly faster, as well as harder to
read.
There was also, on TOPS-10, a TECO that would read the command string and compile it into
machine code, then execute the result. I think it came from Stevens University, but that
may just be a confused memory.
