That's more of a job for a jig called juxt:

This is the TXR Lisp interactive listener of TXR 294.
Quit with :quit or Ctrl-D on an empty line. Ctrl-X ? for cheatsheet.
TXR's car insurance now offers cdr coverage for bumper-to-bumper
protection.

(1 6)

juxt takes functions as its arguments and returns a function.
When that function is invoked, it passes its argument to each
of the child functions, and returns a list of the values.
