Incorrect translation of &. evaluating LHS twice about ruby-next HOT 2 CLOSED

Thanks for the report!

So far, I have only the following idea:

Object.new&.object_id #=> (((__tmp__ = Object.new) || true) && (!__tmp__.nil? || nil) && __tmp__.object_id)

(and the lvar name should be unique in the context (file?))

from ruby-next.

Yes, I think an extra var is needed, just like for some cases of pattern matching.

I think it can be simplified a bit:

Object.new&.object_id
#=>
(__tmp__ = Object.new; __tmp__.nil? ? nil : __tmp__.object_id)

to be closer to the actual behavior, checking with nil.equal?(__tmp__) might be better.
