Package: zsh
Version: 4.3.5-2
Severity: normal

Hello, one of my scripts has broken because of the following change:

$ zsh --version
zsh 4.3.2 (i686-pc-linux-gnu)
$ x=(); echo ${+x[(r)blah]}
0

$ zsh --version
zsh 4.3.5 (i686-pc-linux-gnu)
$ x=(); echo ${+x[(r)blah]}
1

Is the behaviour of zsh's parameter expansion supposed to be stable?

Thanks,

Frederik
