Yes. One reason is that Y-A-E-L is likely to be a much worse language
than Python or TCL. Often extension languages have needlessly cryptic
syntax (e.g. procmail), and/or are missing lots of crucial features
(e.g. the elm filter language).


Put it this way: designing and implementing your own extension
language would only make sense if you think you can do it better or
more easily than by using one of the freely available ones. But the
Python and TCL folks are no fools, and they have been at it for years
now. What would make you think you can do a better job in a week or
so than what they've done over many years?
