Lisp in English

I love to write Lisp as do in English.

Macro: THEREIS

(thereis var in list such that predicate)

Returns t if there is an element such that the predicate satisfies.

Examples:

(thereis x in '(1 3 5) such that (evenp x))
; => NIL
(thereis x in '(1 2 3) such that (evenp x))
; => T
