Description

Consider this script:

Thread.current.thread_variable_set("ab", 12)
puts Thread.current.thread_variable?("ab")
puts Thread.current.thread_variable?(:ab)
puts Thread.current.thread_variable?("ab")

When I put the script above in a file and run it, I got three true as expected:

bash-3.2$ ruby test.rb
true
true
true

But when I copy each line to IRB, I got false on the first check:

bash-3.2$ irb
irb(main):001:0> Thread.current.thread_variable_set("ab", 12)
=> 12
irb(main):002:0> puts Thread.current.thread_variable?("ab")
false
=> nil
irb(main):003:0> puts Thread.current.thread_variable?(:ab)
true
=> nil
irb(main):004:0> puts Thread.current.thread_variable?("ab")
true
=> nil

I expect it to print three true in IRB, just like when I run the script via file.
