Why is there no method to reprint the source within binding.irb?

[olivierlacan]

Description

When using binding.irb, the local source Ruby code is printed when the debugging session starts but if it's cleared there doesn't seem to be a method to reprint it.

# irb_source.rb
def test
  binding.irb
end

test

$ ruby irb_source.rb

From: irb_source_bug.rb @ line 2 :

    1: def test
 => 2:   binding.irb
    3: end
    4:
    5: test

irb(main):001:0>

Pry and byebug both offer a way to reprint the local source around the breakpoint without quitting the session. While it's understandable that binding.irb would have fewer features, this seems like an important one.
