Re: [isabelle] auto and safe with defined variables in locales
At the moment, any assumption like =X is deleted after replacing X
by . As you've noticed, that isn't helpful if constrained by a
locale. We could investigate whether anything can be done about it.

I expected something like:  = X ==> False, but I get just False.
The same is with auto. The reason seems to be the defined variable
In some more complex proofs, this forces me to very often fold/unfold
symbol definitions in my locales (to prevent auto or safe making such
transformations), and this makes the proof scripts more confusing.
Is this behaviour of safe and auto the intended one ?
Is there any workaround to use a defined variable like X, but prevent
safe/auto from making such steps ?
