Re: FORMAT/scanf style input parsing

Lisp has read. Read is nice enough. However, since at least the time of

IFormatProvider interface.

Has lisp ever had support for parsing based on some subset of format
control-string language? The reason I ask is that after porting some old
fortran in the recent past, I realize that i kind of miss having a
way to conveniently parse moderately structured input. I know for
extremely simple things there are libs like SPLIT-SEQUENCE, and cl-ppcre
and parser generators for more complicated parsing. However, there is a
sweet spot for parsers like FORMAT (not to mention the symmetry of
notation).

There's an implementation of (SETF FORMAT):
