Dear all,
maybe someone can help:
How do I remove a rule from the intro! set?
I have tried:
declare <rule>[intro! del]
apply (auto intro! del: <rule>)
(and also with intro instead of intro!),
but both are invalid syntax.
The rule in question is predicate1I, which interferes with by intended
proof strategy.
Best,

Use "rule del" here, either as attribute or method modifier.
