5.3.1 - lot of bad math expression

Hi,

when trying to find a solution/propper settings for the
X=./{etc,bin} ; ls $X   problem I decided to give the latest release aka
5.3.1 a try. However, here I get a lot of errors wrt. the default
completion files e.g. for ls\t like:

_arguments:360: bad math expression: operator expected at `descrs'
_main_complete:341: bad math expression: operator expected at
`lastdescr'
_main_complete:380: bad math expression: operator expected at
`comp_color...'

I guess this version is somewhat closer to ksh than the current one we
have on our systems (5.0.7), and therefore unbraced stuff fails. E.g.

while [[ anum -le  $#descrs ]]; do ... ; done

Is it going to get fixed? If not, what is the best way to do and check,
i.e. make sure, that all files can be used w/o getting into trouble?


BTW: Also I wonder, whether

while (( anum < ${#descrs} )) ; do ... ; done

is a little bit faster than the [[ ]] variant.


Thanx,
jel.

PS: 2 Attachments: my current ~/.zsh{env,rc} - there is no /etc/zshenv
    and /etc/zshrc just contains 'autoload -Uz compinit; compinit -i'.
    /etc/zprofile just exports LOGNAME PATH and set the default umask.
