Re: [isabelle] HOL-Algebra breaks "algebra" method
I decided to look into the matter myself after all and found the
problem: the "normal" algebra method we all know and love is declared in
"Groebner_Basis", but HOL-Algebra also declares an "algebra" method that
shadows the other one.
Of course, one can still access both of them using the fully-qualified
names Ring.algebra and Groebner_Basis.algebra. Still, in my opinion, it
may a good idea to resolve this naming conflict.
For instance, the situation is that currently, proofs using the
"algebra" method break once HOL-Number_Theory is imported (since it
depends on some theories from HOL-Algebra)
