No, it wouldn't. Any object that provides __hash__() and __eq__() can be
used as a key.
Nothing prevents using mutable objects as keys in Python.
Egon Spengler: There's something very important I forgot to tell you.
Peter Venkman: What?
Spengler: Don't use mutable keys.
Venkman: Why?
Spengler: It would be bad.
Venkman: I'm fuzzy on the whole good/bad thing. What do you mean,
"bad"?
Spengler: Try to imagine all life as you know it stopping
instantaneously and every molecule in your body exploding at the
speed of light.
Ray Stantz: Total protonic reversal!
Venkman: Right. That's bad. Okay. All right. Important safety tip.
Thanks, Egon.
