module providing write-once, read-many attributes for Moose


MooseX::SetOnce provides the SetOnce attribute which lets your class have attributes that are not lazy and not set, but that cannot be altered once set.

The logic is very simple: if you try to alter the value of an attribute with the SetOnce trait, either by accessor or writer, and the attribute has a value, it will throw an exception.

If the attribute has a clearer, you may clear the attribute and set it again.
