def binding_n(n = 0)
  Byebug.skip do
    Byebug.current_context.frame_binding(n+1)
  end
end

#byebug(steps = 1) ⇒ Object Also known as: breakpoint

Enters byebug in the current thread after steps line events occur.

Before entering byebug startup, the init script is read. Setting steps to 0 will cause a break in byebug’s subroutine and not wait for a line event to occur. You will have to go “up 1” in order to be back to your debugged program from byebug. Setting steps to 0 could be useful if you want to stop right after the last statement in some scope, because the next step will take you out of some scope.
