Configuring Vale for another filetype, only in a specific block.

[zetashift]

So I'm trying to do get Vale to do following:

{{
  # My blog
  
  Hello, this should be checked by Vale in my editor.

}}
aVariable = "this shouldn't"

Anything in {{ ... }} should be checked by vale(filetype is .u), as a markdown block, but anything else should be ignored. Is this possible?
Usecase: in Unison it's possible now to write a blogposts using their Doc format: https://share.unison-lang.org/@unison/blog-engine

This is not possible currently.

Thank you! That's too bad to hear, but it's quite a specific feature request anyway 😄
