Andreas is exactly right. Aside from anything else they're both special
selectors as well so the compiler tries to optimise for them doing the
'normal' thing. @ is actually quite hard to make do anything other than
I really think that comma is a good selector to use, since we really are
concatenating elements on to a path. People really do need to understand
that filenames are not strings and you can't properly build them by simply
sticking strings together with slashes in there somehow. There's a bunch of
truly awful code lying around the image that makes that assumption and it
needs to be excised, root and branch.
