This is not the bug you think it is.

"set -A myarray" is declaring a *global* (not local to "arrtest") array
named "myarray".  It's exactly equivalent to writing

	myarray=()

"typeset -x myarray" then declares a local scalar, also named "myarray",
which hides the global.  This is a result of a recent change that makes
"export" equivalent to "typeset -gx" and not equivalent to "typeset -x".
This is a known bug.  For the time being, you should use "export" when
you mean "export".

    function arrtest
    {
    	set -A myarray
	export myarray
	myarray[1]=arrtest
	print $myarray
    }

However, since arrays can't be exported in the first place (zsh marks
them exported internally, but does not put them in the environment) it's
almost certainly the case that you shouldn't have used "typeset -x" in
the first place.
