Research direction

Start by reviewing the existing stack-switching proposal's prompt and suspension semantics. Determine how a suspension can identify the exact prompt bracket it targets, and define completion as preventing accidental capture by an inner prompt without requiring inefficient re-suspension. No implementation files or tests are named in the issue.

Written by the indexing model from the issue text.

Description

Being able to specify exactly which prompt bracket a particular suspension refers to is important for safety. This will help to prevent so-called accidental capture of a suspended computation by the presence of an inner (later) prompt bracket.

In addition, even if it is possible to simulate this by suspending to an inner prompt bracket and then re-suspending if that prompt bracket turns out to be incorrect is unnecessarily inefficient.
