process substitution bug?

[Alexey Tourbin <at@xxxxxxxxxxx>]

Hi,

When I wrap some command into a function, process substitution
no longer works:

$ =diff <(echo 1) <(echo 2)
1c1
< 1
---
> 2
$ diff () {
function> =diff "$@"
function> }
$ diff <(echo 1) <(echo 2)
/usr/bin/diff: /proc/self/fd/11: No such file or directory
/usr/bin/diff: /proc/self/fd/12: No such file or directory
$ echo $ZSH_VERSION
4.2.4
$
