[isabelle-dev] Eisbach and HOL-Analysis

[Lawrence Paulson]

This might be very interesting! I assume it’s for proving theorems about distances and norms for type classes such as metric_space and real_normed_vector?

I don’t know a lot about Eisbach, but it seems to be a fundamental facility so surely there is a case for including it in HOL itself.
