That's why I think we should have an explicit "builtin" command, i. e.
command with the name "builtin" that will always run the corresponding
builtin command, no if there is a "command alias" or not - similar to
the bash command:
builtin shell-builtin [arguments]
Execute the specified shell builtin, passing it
arguments, and return its exit status. This is useful
when defining a function whose name is the same as a
shell builtin, retaining the functionality of the
builtin within the function. The cd builtin is commonly
redefined this way. The return status is false if
shell-builtin is not a shell builtin command.

I don't like to use quoting (of any kind) for this because this
already has certain meaning in the shell. Also, this would be more
effort to implement that the "builtin" command I suggested.
