Make Heredocs a first class citizen

Make Heredocs a first class citizen

Hi All,

I’ve been struggling to implement heredoc highlighting. I’ve read various
implementations and they all differ.

It got me thinking that it would be nice is emacs could provide syntax
highlighting for heredocs in the same way it does for multi-line string and
multi line comments as syntactic constructs.

Seeing as multiple languages support heredoc syntax it seems like a good
fit for a core feature.

As I’m struggling to do this myself I don’t feel like I can be the person
to implement this.

Cheers,
Reza

In the abstract I agree, but I'm not sure how easy it is and how much
can really be shared.  I think every language has slightly different
rules about how (and where) a heredoc starts, so I suspect it'll be hard
to share that part.  And the "match the end" part is the easy part
anyway, so there's a risk that sharing it may not bring very
much benefit.
