Aaron Patterson	93d72131bc	add the casting node to the AST at build time ... If we add the casting node to the ast at build time, then we can avoid doing the lookup at visit time.	2014-03-24 16:26:09 -07:00
Ernie Miller	6e638bba59	Add equality to ALL THE THINGS (that matter) ... People are often trying to use ARel nodes inside ActiveRecord, and when they do so, lots of things can break, because ActiveRecord relies on Array#uniq and sometimes hash key equality to handle values that end up in wheres, havings, etc. By implementing equality for all the nodes, we should hopefully be able to prevent any nodes (even nodes containing other nodes) from failing an equality check they should otherwise pass, and alleviate many of these errors.

Ernie Miller	c78227d9b2	Include Predications in Grouping ... Also, removed unused ordering.rb file, since it is identical to the one being created in unary.rb already, and isn't required anywhere.	2012-05-19 11:10:47 -04:00
