[racket] Is there a name for: (lambda (x) (x)) ?

Folks,

Am I missing something really basic here?

I have a list of thunks. I want to iterate over the results of these
using a high-order function ... map, for-each, filter (et al).

The only way I can find to do it is:

(map (lambda (x) (x))
   (list
     (lambda () 1)
     (lambda () 2)
     (lambda () 3))) -> '(1 2 3)

Is there a standard name for the (lambda (x) (x)) in racket?

Or do I have to write my own (define (call x) (x))?

Tim
