Assign method call to hash value?

[Daniel Perrett]

Apologies: so after consultation with #perl on IRC, my question has
been answered - Moose (for reasons I don't yet know) does stuff like

has 'foo' => ( is => 'rw' )

which would incorrectly be treated as

has 'foo' => 'rw'

So ignore my previous post.
