Making a lambda-expr more like a fn

One of the changes to CL2 that bit me has been that
raw lambda's can no longer be funcall'd (or apply'd)
directly.
With CMULisp, I have remedied this by coercing the lambda
into a function first:
(setf (org-lexpr p) (coerce lexpr 'function))
But CCL::COERCE-TO-FUNCTION won't have it:
> Error: value (LAMBDA (WLIST &AUX X1) (SETQ X1 (NTH 0 HISTORY)) (VALUES (+ (CAR WLIST) (* (NTH 1 WLIST) X1)) (LIST 1.0 X1))) is not of the expected type FUNCTION.
> While executing: CCL::COERCE-TO-FUNCTION
I have also tried prepending the #' (function) abbrev., but
that result couldn't be funcalled either.
I was able to get what I wanted compiling the form instead. However, in
this application, I would like very much to avoid the compilation overhead
if at all possible. Can I?
