The language can help here. q{stuff} is a "token string" which 
presumably contains code, whereas the other strings presumably don't. In 
my editor, q{code} comes off as highlighted.

So I think in the future it's a good bet for both programmers and 
editors to consider q{} quotes as containing code.
