Any classes that don't implement #blank? will fall back to Object's implementation, which checks whether #empty? is defined before either using #empty? or implicit truthiness. Since checking whether #empty? is defined is expensive, some core classes (Array/Hash) alias #blank? directly to #empty? to skip the respond_to? check. This commit applies the alias optimization to Symbol. #blank? is called on Symbols for many Active Record query methods (select, includes, group, order, joins, etc.) so it seems reasonable to define the #blank? alias on Symbol as well. |
