+1. You might still run into null elision, though.

Hang on. Why would it matter which style of quotes would have been
used? Considering «eval "$foo${(q)bar}$baz"», normally $foo would be
constructed to end on inter-token whitespace, and then the number of q's
wouldn't matter, whether it's 1, 2, 3, 4, q+, or q-.
