Thanks for the explanation.

Is the following behaviour also intentional?  Testing a key's presence
in the associative array in different ways gives different results:

    % bindkey foo bar
    % () { print $(( $argv[(I)bar] > 0 )) } ${(k)widgets}
    1
    % print ${+widgets[bar]}
    0

I ran into this while trying to clarify the docs of $widgets in line
with your answer.

Thanks again,

Daniel
