Research direction

Start by running the reported lbf-comp command against goldens/good/work-dir, goldens/good, and goldens/good/LambdaBuffers.lbf, then inspect issue #75 and the compiler changes it introduced. Compare the command's timing with the pre-#75 behavior if available; the regression is addressed when the affected compilation path no longer shows the reported performance degradation.

Written by the indexing model from the issue text.

Description
