Probably not, though I do this myself, lol...
Perl will see that there're no variables to interpolate in the string
at compile time, and the optimizer will likely make a literal out of it
exactly as if you had used single-ticks. I'd say that applies to
interpolated constants like \n as well, though I'll wait for more
knowledgeable minds to confirm or deny that.
So in short, I doubt it really matters at all.
