      description "Move into the given object or leave the current context."

help_message(<<~HELP)
        Usage: cd ([target]|..)

IRB uses a stack of workspaces to keep track of context(s), with `pushws` and `popws` commands to manipulate the stack.
        The `cd` command is an attempt to simplify the operation and will be subject to change.

When given:
        - an object, cd will use that object as the new context by pushing it onto the workspace stack.
        - "..", cd will leave the current context by popping the top workspace off the stack.
        - no arguments, cd will move to the top workspace on the stack by popping off all workspaces.

Examples:

cd Foo
          cd Foo.new
          cd @ivar
          cd ..
          cd

        when ""
          # TODO: decide what workspace commands should be kept, and underlying APIs should look like,
          # and perhaps add a new API to clear the workspace stack.
          prev_workspace = irb_context.pop_workspace
          while prev_workspace
            prev_workspace = irb_context.pop_workspace
