Literally the opposite. We can make and use so many, because writing them is more or less the same. We can quickly throw together a new lisp for a new platform or such and use it without problem.

		Technically when you write in the domain, you are effectively making your own Lisp and then using it. It’s one of the amazing things that macros can do.
