Warning causing evaluation to fail

[tgodzik]

I am getting:

compilation failed:
parentheses are required around the parameter of a lambda
Use '-Wconf:msg=lambda-parens:s' to silence this warning. [quickfixable]
Scala 3 migration messages are errors under -Xsource:3. Use -Wconf / @nowarn to filter them or add -Xmigration to demote them to warnings.
Applicable -Wconf / @nowarn filters for this fatal warning: msg=<part of the message>, cat=scala3-migration

though the workspace doesn't use -Xsource:3

MAybe we could at least silence the warning?
