This is the `loop' macro from cl.el.  It mimics a Common Lisp idiom
which, strangely enough, looks nothing like Lisp but is sort of a DSL
for specifying imperative loops.  You can find the documentation by
doing C-h i (to open the Info manual in Emacs) then following the =E2=80=9C=
CL=E2=80=9D
link.

(One of the coolest features is that it is all implemented via macros,
so the compiler automatically unrolls it into a native Lisp loop.  Thus
the performance hit, if any, is negligible.)

Given the fact about loop, let* isn=E2=80=99t really applicable.
