It took some debugging to come across this one:
irb(main):043:0> w
NameError: undefined local variable or method `w' for main:Object
from (irb):43
from /home/ravi/.rbenv/versions/2.2.3/bin/irb:11:in `<main>'
irb(main):044:0> w = w
=> nil
irb(main):045:0>
Yeah, right, so what?
It leads to "find the nil" fun-hunts in cases such as:
irb(main):057:0> mispelt_argument =
Array(mispelt_argument).flatten.uniq.map(&:name)
=> []
Are there any cases in which this "feature" is actually useful, or is it
an unintended parser functionality?
