Description

While testing converting our project to BrightScript, we noticed the Language Server didn't like the multi-dimensional array access syntax array[x, y, ...], even though it's supported in the base language.

Research direction

Start by tracing the BrightScript language-server parsing and validation path for array access, using the reported array[x, y, ...] syntax and the linked BrightScript array-operator reference as the expected behavior. Done means valid multi-dimensional array access is accepted without a language-server diagnostic, with coverage for the syntax if the existing test structure provides a suitable place.
