String interpolations with conditionals have unexpected results.

MIRB

# Should be an empty string
> "#{'' unless true}"
 => nil
# OK
> "#{'' unless true}test"
 => "test"
# Should be a String, not main
> "#{'' unless true}test".length
(mirb):7: undefined method 'length' for main (NoMethodError)

IRB

irb(main):001:0> "#{'' unless true}"
=> ""
irb(main):002:0> "#{'' unless true}test"
=> "test"
irb(main):003:0> "#{'' unless true}test".length
=> 4
