Description

Currently, both Uint and Int implement some (partially) variable time algorithms. Is there interest for full-vartime mul and div operations? I have a local PR lined up which I would love to polish up and prep for merge.

Research direction

Read the issue discussion and inspect the linked local PR first, focusing on the existing Uint and Int multiplication and division operations. The scope is not yet settled: done would require agreement on supporting full variable-time mul and div operations and a clear path for preparing the work for merge.
