EQ newbie question

[smithzv]

Another relic from that paper that is somewhat useless today but still part of CLISP is atom.

You find ATOM to be useless?

Code: Select all

#'atom == (lambda (x) (not (consp x)))

I find I use it all the time when traversing a syntax tree.

Not useless as a function but, like eq, has a misguiding name. Must say I prefer (not(consp x)) any day.
