Comments on Lush

I recently read this (mostly flattering) review of Lush.

The review starts with "This is the best Lisp I have yet used" with
flattering comments. The same review also says "this is also
the UGLIEST Lisp I have yet used". I could not agree more.
Lush was not built for elegance, but as a tool for attacking
large scale machine learning problems. We want it to get
the work done and stay out of the way.

Our sympathic reviewer is puzzled by the fortran-like
qualities of CLush. This comes handy for heavy
numerical calculations. During the last seven years,
a CLush program has been reading about 25,000,000
check amounts per day! (serious: see [1].)
