Hi,

I think this makes sense. SLY/SLIME for CL do something similar
with #'make-instance, for instance.  As soon as you type the function name
or class name and the autodoc system recognizes it, it switches to the
showing you the args for that function instead.

The patch shouldn't be terribly difficult to adapt, since I've not
significantly
touched the client-side logic (as in clients of eldoc).

I think you can try doing so. I'll keep this on my radar,
João
