Ouch! I tried to make an attempt at merging the examples from
Moose/Util/TypeConstraints.pm. Sorry if I was off target.

So the answer is use 'as'.
subtype 'IndexType'
=> as enum( $_, qw[foo bar baz]),
=> message { "index_type ($_) must be one of ". join ',
', qw(foo bar baz)},
has 'index_type' => (
isa => 'IndexType',
is => 'ro',
required => 1,
);
Thank you, that works and I'm getting my message.
Dp.
