    See my first example. It appears that what looks like a string to a fat comma is diffferent to what looks like a string to a leading hyphen.
    my %a = (keys   => 'v1',
         values => 'v2');

    gets stringified correctly, but:
    my %a = (-keys   , 'v1',
         -values , 'v2');

    [download]
    does not.
