It's the opposite: zsh is more lenient about braces, turning $a_host[ ]
into an array expression with an incorrect subscript.  So your fix is
fine.  Having "setopt ksharrays" would fix this, and this option is used
in compatibility modes, so indeed if you were in sh emulation as
explained by Bart this will work without modification.  The emulation is
a much better general solution---there are other compatibility issues,
many of the most important of which are listed in the FAQ
(http://zsh.dotsrc.org/FAQ/zshfaq02.html#l10).
