Global definition of 'with' function in Kernel module breaks rspec functionality

[PhilippOtto89]

Hey developers,

in our project we use facets and RSpec. Rspec has an awesome feature to check if a function was called with parameters like

expect(dbl).to receive(:foo).with(1, anything, /bar/)

Unfortunately this breaks because there seems to be a global override of this function in facets. We receive the error

ArgumentError:
wrong number of arguments (given 3, expected 0..1)
/Users/philip.otto/.rvm/gems/ruby-2.6.0/gems/facets-3.1.0/lib/core/facets/kernel/with.rb:15:in `with'

And this file indeed contains a definition of this function

module Kernel
  def with(obj=self, &block)
    obj.instance_eval(&block)
  end
end

Is this global definition really necessary since it seems to interfere with other implementations?

Thanks for reading my question and have a nice day guys!
