# Description Partialy addresses #13868. `try` does not catch non-zero exit code errors from the last command in a pipeline if the result is assigned to a variable using `let` (or `mut`). This was fixed by adding a new `OutDest::Value` case. This is used when the pipeline is in a "value" position. I.e., it will be collected into a value. This ended up replacing most of the usages of `OutDest::Capture`. So, this PR also renames `OutDest::Capture` to `OutDest::PipeSeparate` to better fit the few remaining use cases for it. # User-Facing Changes Bug fix. # Tests + Formatting Added two tests.
