Kernel.y interferes with code relying on method_missing#664

Good day,

I have coordinate objects in protobuf which have a .y attribute defined, but rely on method_missing to trigger calls to C.
Kernel.y intercepts the message and gives me an unexpected result.
I believe other systems which also rely on method_missing like nokogiri will cause the same trouble when trying to access an arbitrary "y" property in a document.

Can we rename the "y" patch to Kernel, to something less common, please?

psych/lib/psych/y.rb

Line 5 in 21f051b

defy *objects

Otherwise people who use x,y,z coordinates get adverse effects and have to implement a workaround like the following.

defysend(:method_missing,:y)end

Even "yy" would be better. Thank you :)

                          Good day,
                          I have coordinate objects in protobuf which have a .y attribute defined, but rely on method_missing to trigger calls to C.
                          
Kernel.y intercepts the message and gives me an unexpected result.
                          
I believe other systems which also rely on method_missing like nokogiri will cause the same trouble when trying to access an arbitrary "y" property in a document.
                          Can we rename the "y" patch to Kernel, to something less common, please?
                          psych/lib/psych/y.rb

                          Otherwise people who use x,y,z coordinates get adverse effects and have to implement a workaround like the following.
                          defysend(:method_missing,:y)end
                          Even "yy" would be better. Thank you :)
