} Plus you don't need all those (@)'s once parameter substitution already has

} (can't quite remember if the trick of putting double quotes in the middle
} made its way back

The quotes in the middle is in 3.0.7, as part of the "minimal forwards
compatibility" effort.

There is a small bug with them in both versions, though; you can't take
the length of the quoted part:

zagzig[57] echo ${#"${(f)$(<file)}"}
zsh: bad substitution
zagzig[60] echo ${#${"${(f)$(<ChangeLog)}"}}
8017

It works with ${=...} and ${~...}, but not with ${#...}.
