I don't think I get that yet. Let's say we have
(cl-flet ((f (lambda () (list 1 2))))
(f))
In this case, the code for F will be run in the body of the
flet. Doesn't that qualify as being run later, as you describe above,
ignoring the "non-instrumented" part, maybe?
(Just from the perspective of behaviour, C-u C-M-x on the flet above does
seem to do what I'd expect: the call to F let's me step into the
body of the lambda.)

I'm afraid I know nothing about coverage, so I can't say something
halfways intelligent to that.
