Debug evaluates code in frame.eval_binding, not frame.binding

irb(main):001> debug
irb:rdbg(main):002> tc = DEBUGGER__::SESSION.instance_variable_get(:@tc)
#<DBG:TC 1:running@a.rb:1:in `<main>'>
irb:rdbg(main):003> foobar = 1
1
irb:rdbg(main):004> tc.current_frame.binding.local_variables
[:_]
irb:rdbg(main):005> tc.current_frame.eval_binding.local_variables
[:foobar, :tc, :_]
