Support for multi-language files in VSCode

[jtrakk]

Hello, I'm writing to mention that there is an issue being discussed at VSCode GitHub about supporting files with multiple embedded languages. The question is whether it would be useful to have an attribute defining the current active language at the cursor location.

I think the Racket community is especially sophisticated about language embedding, so you or "Magic Racket" VSCode extension maintainer @Eugleo might like to participate in that conversation. If nothing seems relevant, feel free to close and ignore this issue. :slightly_smiling_face:
