local_variable_set

        # Binding.local_variable_set

(from ruby core)
---
    binding.local_variable_set(symbol, obj) -> obj

---

Set local variable named `symbol` as `obj`.

    def foo
      a = 1
      bind = binding
      bind.local_variable_set(:a, 2) # set existing local variable `a'
      bind.local_variable_set(:b, 3) # create new local variable `b'
                                     # `b' exists only in binding

      p bind.local_variable_get(:a)  #=> 2
      p bind.local_variable_get(:b)  #=> 3
      p a                            #=> 2
      p b                            #=> NameError
    end

This method behaves similarly to the following code:

    binding.eval("#{symbol} = #{obj}")

if `obj` can be dumped in Ruby code.
