Subject: suprise with -=
Date: Sun, 18 Oct 2015 22:46:49 -0700	[thread overview]
Message-ID: <562483C9.1060602@eastlink.ca> (raw)



    test1 ()
    {
    integer first=1
    integer second=2

    ((first+=second))
    echo $first

    ((first-=second))
    echo $first

    first+=second
    echo $first

    first-=second
    echo $first

    }

    3
    1
    3
    test1:15: command not found: first-=second
    3


That's a bit of a surprise, why is zsh fussier with '-=' than with '+='?
