I didn’t mean to imply that [0, 1, 0] syntax is especially going to be more difficult than any of the previous syntactical changes made in Scala 3.x lifetime. My meta-ask/reminder for the Scala Improvement Process is to perform environmental impact assessment prior to the acceptance of the proposals, as specified in Process Specification as follows:
Once the implementation is deemed stable, including appropriate tests and sufficient support by the tooling ecosystem, the implementers and reviewers can schedule the SIP to the next Committee meeting for final approval.
I just wanted to remind the stakeholders (including myself as tree-sitter-scala contributor) that this hasn’t been the case for recent SIPs, and this SIP would be a good opportunity to get on track.
