When trying to use STI with dm-is-list

I got the following error

method `execute_after_inherited_nan_hook_stack' not defined in Default::LikelihoodLabel
/Users/dneighman/.rvm/gems/ruby-1.8.7-p174/gems/dm-core-1.0.0/lib/dm-core/support/hook.rb:357:in `remove_method'

The reason for this error is pretty simple:

http://github.com/datamapper/dm-core/blob/master/lib/dm-core/suppor...

In the if test on that line it's checking the before_hook_name rather than the after_hook_name.
