Subject: Re: Should undefined behavior be encouraged in Emacs?

Undefined behavior is something that is left to the implementation,
and the programmer who invokes it cannot expect anything in
particular.
This definition is used in standards development, and presumes that
we're talking about a spec that might have various implementations.
However, Emacs is one specific program, not a spec. Thus, concepts
from standards development, about the relationship between the spec
and its various implementations, may not transfer naturally. I don't
see what "undefined behavior" would mean in the case of Emacs.
