Yes, it's circular. In an abstract system like a programming language,
where the definition only needs to describe behaviour of that system,
what is your objection to circularity of definition?

A great many abstract systems designed by humans are defined in terms
that are ultimately circular. This does not in any way hinder them from
being useful definitions of useful systems.
