[Maxima] Limits and assumptions

I have a question about the interaction between limits (perhaps also
integrals?) and assumptions. See the floor(x) example in the
Maxima 5.19.1 http://maxima.sourceforge.netUsing Lisp SBCL

(%o1) [x < - 2]
(%o4) limit floor(x)
x -> 0
(%o6) [x < - 2]
In some sense, this makes sense, since I assumed x<-2, so the limit
doesn't make sense, as opposed to the y example. But should an error
maybe be raised instead? I assume this is how I am supposed to
interpret the output, but ? limit; doesn't indicate this either way.
Or should it not matter, as if x were treated as a dummy variable? In
which case I should get und. And does this occur sometimes in
integrals (I don't know)? Thank you as always for the help!
