I see now that I was wrong here - the test is performed at run-time.

Not at run-time: when the `define-key' call is evaluated, the symbol
must be bound, else you would get an error.

But some way or the other something has to decide how to interpret a
symbol.  If you want to use the same notation for the cases, you need to
use some kind of heuristic: in theory a symbol might name a function and
might be bound to a keymap at the same time.

And instead of `eval' better use `bound-and-true-p' - you know that you
look at a symbol.  You could also check whether the `symbol-name' ends
with "...-map".
