Hi John,

I'm not sure whether you were ironic or not, but assuming you were not,
here's my answer: no, I cannot /identify/ them, but sometimes I can
/suspect/ them.  More seasoned developers should make the decision,
though.

Sometimes I look up some function or command, and I'm surprised it's
defined in C and not Elisp.  I could start making notes about those
situations.

As I said, `self-insert-command' seems a natural candidate.  It is
probably almost never called from Elisp code, and I would guess it's
similar for C code.  (One exception might be keyboard macros - if yes,
this might be a performance bottleneck.)

And btw: is there a way to search for functions according to the
filename they are defined in, possibly using a regex, so that one could
search e.g. for functions defined in C by specifying "\.c$"?
(Drew?  Icicles?)
