In this example:

(module-static #t)

(define-simple-class <A> ()
((an-identity-meth name)

(define a (<A>))

;; Inexpensive:
((as <A> a):anIdentityMeth 'foo)
;; Expensive:
(a:anIdentityMeth 'foo)
;; Expensive:
(*:anIdentityMeth a 'foo)

the last call gives the following warning, letting us know that an expensive runtime lookup will be performed for each invocation:

types.scm:15:1: warning - no accessible method 'anIdentityMeth' in java.lang.Object

The feature request is that the second-to-the-last call also give us a warning.
