So far nobody has stepped up to defend me, so I'll accept that maybe
people do think it is crazy. What I'm really confused by is why we have
a new weird ugly language like YAQL (sorry, it, like JQ, is hideous),
and that would somehow be less crazy than a well known mature language
that has always been meant for embedding such as javascript.
Anyway, I'd prefer YAQL over trying to get the intrinsic functions in
HOT just right. Users will want to do things we don't expect. I say, let
them, or large sections of the users will simply move on to something
else.
