It doesn't work correctly for me on 5.5.1 either; I can confirm the
broken behavior:

	hobbes% zsh -f
	hobbes% setopt ksharrays
	hobbes% typeset -A a
	hobbes% ((${+a[key]})) && print should not echo
	should not echo
	hobbes%

Although interestingly enough:

	hobbes% zsh -f
	hobbes% setopt ksharrays
	hobbes% typeset -A a
	hobbes% [[ -v a[key] ]]
	hobbes% ((${+a[key]})) && print should not echo
	hobbes%

This is the with the zsh currently packaged on arch:

	bobbes% zsh --version
	zsh 5.5.1 (x86_64-unknown-linux-gnu)
	hobbes%

When I get home I'll try compiling the current HEAD to see if the
behavior has changed.
