Subject: [ruby-core:63636] [ruby-trunk - Bug #10024] Array injection of ternary operators injects boolean rather than ternary result

Issue #10024 has been updated by Patrick Metcalfe.


The #<< has a higher precedence than the ternery operator.

Bug #10024: Array injection of ternary operators injects boolean rather than ternary result

----------------------------------------
The following code:

a = []
a << ''.blank? ? 'blank' : 'not blank'

puts a

renders [true].

I would expect it to render ['blank']

If I wrap it in parenthesis it does work.

a = []
a << ( ''.blank? ? 'blank' : 'not blank' )
puts a # ['blank']

it seems like the logic internally is perceiving this function as:

(a << ''.blank?) ? 'blank' : 'not blank'

Which seems illogical.
