There are a few problems with /var:
//var % $+ x = 1 | echo -a %x
%x is set to
= 1 when it should be set to
1//var $+(%,x) = 1 | echo -a %x
This gives an error.
For both of the above, if you use
//set -u instead of var they work fine.
Sorry if this has been reported before, but the search engine gives far too many results for /var, var, /set, set, etc.
