Yes, although it's counter-intutive there's no real performance hit
from double-quoting constant strings.

The one that bugs me is when I see people doing this:

$hash{"$key"}

instead of this:

$hash{$key}

That one is actually in the perlfaq man page, but I still see it all the
time.  The performance difference is very small but it does exist, and you
can get unintended results from stringifying some things.
