Getting SyntaxError: (irb):4: syntax error, unexpected kIF_MOD when assigning hash key the value of an if expression.

Here is the code I am pasting in:

@something = Hash.new

@d = {
  type:  if @something.is_a?(Hash)
           'hash'
         elsif @something.is_a?(Array)
           'array'
         else
           'unknown'
         end,
  foo: "bar"
}

puts @d

** Jruby 1.7.19 **

Code pasted into jruby 1.7.9 rib.

rvm use jruby-1.7.19 do irb
jruby-1.7.19 :001 > @something = Hash.new
 => {}
jruby-1.7.19 :002 >
jruby-1.7.19 :003 >   @d = {
jruby-1.7.19 :004 >       type:  if @something.is_a?(Hash)
jruby-1.7.19 :005?>                'hash'
jruby-1.7.19 :006?>              elsif @something.is_a?(Array)
jruby-1.7.19 :007?>                'array'
jruby-1.7.19 :008?>              else
jruby-1.7.19 :009 >                  'unknown'
jruby-1.7.19 :010?>              end,

Works as expected on 9.1.9.0:

irb(main):001:0> @something = Hash.new
=> {}
irb(main):002:0> 
irb(main):003:0*   @d = {
irb(main):004:1*       type:  if @something.is_a?(Hash)
irb(main):005:2>                'hash'
irb(main):006:2>              elsif @something.is_a?(Array)
irb(main):007:2>                'array'
irb(main):008:2>              else
irb(main):009:2*                  'unknown'
irb(main):010:2>              end,
irb(main):011:1*       foo: "bar"
irb(main):012:1>   }
=> {:type=>"hash", :foo=>"bar"}
irb(main):013:0> 
irb(main):014:0*   puts @d
{:type=>"hash", :foo=>"bar"}
=> nil
