Before loading the models:
Sequel::Model.plugin :subclasses
After loading the subclasses:
Sequel::Model.descendents.detect{|c| c.table_name == :foo}

There isn't currently a way to do so, as it's possible to have models
that use datasets not based on tables or based on multiple tables, as
well as multiple models that use the same table. You could always
create a plugin to do so, by having the model register itself in some
shared hash keyed on the table name.
