Yes, I mean that in JS is used some similar (although as you say with varia=
bles).
I would prefer to use this "feature" with nowdoc. Normally, strings with va=
riables are moved to views, while large literals (like queries) are added i=
nline.

I see this purpose as a simplification of Nowdocs. Just like `[]` with `arr=
ay()`.

ups!, I'm sorry...but, look at:

Markdown is not broken here due to ``` of code.
