Hi!
Thank you for your report.
Sorry for answering that late.

I don't know version 1.x but at least in 2.x it is
working as documented. What you try above
is similar to this chapter
http://search.cpan.org/~schwigon/Class-MethodMaker-2.12/lib/Class/MethodMaker.pm#Naming
although there an array is used.

Not really; $f->hash() without arguments should return the
value of, well, a member called "hash". Giving values inside
the parens, $f->hash(FOO => $BAR), will set the value
of the member called "hash". That's why it complains
when you don't give it even number of elements.
Your example will be more clear if you name the
member "foo" instead of "hash":
use Class::MethodMaker
[ hash => [ 'foo' ],
new => ['new']
];
and then use
$f->foo(...)
everywhere.
I will close the bug, because I'm quite certain about it.
Anyway, of course I could also be horribly wrong. :-) Then
feel free to reopen it again.
Thanks.
Kind regards,
Steffen
