Description

I've found that I can't type a certain type of code I maintain, where it'd make sense to do so.

operation = ["+"]
operation << 1
operation << 2

I'd like to type this as a tuple of a given type at the head, and variable values of same type at the tail, smth like operation: [String, *Integer], but the parser does not support that.

Research direction

Start by locating the RBS parser handling for tuple types and any existing tuple syntax tests. Confirm how a fixed head followed by a repeated element type should be represented, then add coverage for [String, *Integer]; done when the syntax parses successfully and the expected tuple type is accepted.
