Christoph Thiede uploaded a new version of Compiler to project The Inbox:
http://source.squeak.org/inbox/Compiler-ct.422.mcz

==================== Summary ====================

Name: Compiler-ct.422
Author: ct
Time: 21 March 2020, 11:07:22.79756 pm
UUID: ab5eff73-dbf5-7a4e-96e7-9991c9068f16
Ancestors: Compiler-nice.420

Proposal: Allow to cancel compilation if an unused variable is detected

This way it feels more consistent with UndefinedVariable and UndeclaredVariable.
