While I can't immediately think of a practical problem with this, I'm hesi=
tant at the idea of adding yet more ways of quoting strings; it means more =
for users to learn, more for third party parsers to implement (including ex=
actly the syntax highlighting tools you're going to help), and in the worst=
 case, more edge cases that can lead to security issues=2E

I don't know about other editors, but PhpStorm at least also recognises an=
 in-line comment explicitly labelling any string, which if anything seems m=
ore explicit:

$query =3D /** @lang mysql */"SELECT * FROM foo";
