No.  The compiler can do constant folding of such expressions.

I guessed, that maybe the compiler will close the literal when it finds more than half the number of backticks than the beginning (nothing implied this behaviour just tried it and I know that it might be very suprising in other cases). I have tried with the latest early access compiler and (not too suprisingly) it didn't behave this way and simply failed when starting the literal with a backtick.
