Topic

A programming feature (e.g. APIs, tweaks, changes, etc)

Why are you making your suggestion?

Luau does not natively support variables prefixed with a $. As such, using a custom macro symbol like $ makes it much harder to develop Microcontroller code using generic Luau tooling like luau-lsp

What do you propose? What should change, or what should be added?

Allow the use of $ macros for compatibility, but also provide normal function equivalents for each
