bug#23461: perl-mode: Displaying HERE-docs as strings instead of comments [PATCH]

[Stefan Monnier]

> Investigating how to fix this leads to the longer story.  There are two
> possible approaches:
>
>   1) use a string-style syntax (generic string) instead of c-style
>      comments to flag HERE-documents.  That way, font-lock picks up the
>      correct face automagically.
>
>   2) Keep HERE_docs as c-style comments, but change the face mapping by
>      injecting a function into font-lock-defaults which applies the
>      string face to c-style comments.

3) Use `font-lock-syntactic-face-function`?
