I'm not quite sure what you mean by "one can," but that's how the simple
form of Common Lisp's loop macro works.  Friendlier looping constructs
are built with other macros on top of that one and/or its underlying
mechanism.¹

¹ The underlying mechanism is the moral equivalent of a Python suite
that can also contain tags and unconditional jumps to those tags, aka
"goto"s.
