I do not know how ContextL expands its method expressions. If they are
unnamed lambda lists, then they will not show with names in the debugger
stack trace, while if they are named lambda lists they show with proper
names. See for instance

(defvar *b*)

(defvar *a* #'(lambda (x) (declare (optimize (debug 3))) (cos x)))

(defvar *b* #'(ext:lambda-block foo (x) (declare (optimize (debug 3))) (cos
x)))

When compiled and loaded, the following session takes place. Only in the
second case there is a meaningful name in the backtrace

(declaim (optimize (debug 3)))

(defvar *b*)

(defvar *a* #'(lambda (x) (declare (optimize (debug 3))) (cos x)))

(defvar *b* #'(ext:lambda-block foo (x) (declare (optimize (debug 3))) (cos
x)))
