Feature #8600: Recognize variables declared in if modifier at end of line

(({2.0.0 (main):0 > .ruby -v
ruby 2.0.0p195 (2013-05-14 revision 40734) [x86_64-darwin12.3.0]
2.0.0 (main):0 > ([0,1,2])[i] = 1.0 if i = ['seconds'].find_index('seconds')
NameError: undefined local variable or method `i' for main:Object
from (pry):1:in `__pry__'}))

Is it possible to get rid of this kind of error?  Especially since it doesn't matter what the value of the variable is so long as it's defined.

(({2.0.0 (main):0 > i = 10000
=> 10000
2.0.0 (main):0 > ([0,1,2])[i] = 1.0 if i = ['seconds'].find_index('seconds')
=> 1.0}))
