Syntax highlighting inside multi line string

[sebader]

Is your feature request related to a problem? Please describe.
I don't know if this is even technically possible, but it would be awesome if inside a multi line string we could get at least basic syntax highlighting. Maybe only for the most common use cases like JSON, YAML, XML. You could even have the user state which language it is like

var myXml = '''xml
<hello>
   world
</hello>'''

Currently it this beautiful big (in my case) brown blob ;)

Describe the solution you'd like
Have it light up nicely

I had a feeling this would come up 😄

;) And I left out the part that I want interpolation but I think the example speaks for itself :P

My personal opinion: We do have some options for supporting this, but it feels like if we're starting to inline complex snippets from other languages, we should instead look to supporting this through includeFile() (#471), so that real language validation can occur on top of just syntax highlighting, and we're less limited in terms of escaping.

+1 for complex things being done in includeFile(), then you can open that file and use the actual language server of that file rather than some shimmed-in syntax highlighting.

+1 agree with @anthony-c-martin, I suggest we close this.
