The following gives syntax error on ruby 2.1.3

h = { key: if true
             "yes"
           else
             "no"
           end }

puts h.inspect

/usr/local/rvm/rubies/ruby-2.1.3/bin/ruby x.rb
x.rb:1: syntax error, unexpected modifier_if
h = { key: if true
             ^
x.rb:3: syntax error, unexpected keyword_else, expecting end-of-input
