Common Lisp Progamming Rules

Much of the wisdom of Common Lisp has been lost and left to be rediscovered by new generations of programmers. The following "rules" have not been lost to time, though.

  • Greenspun's Tenth Rule: Any sufficiently complicated C or Fortran program contains an ad hoc informally-specified bug-ridden slow implementation of half of Common Lisp.
  • Strandh's Thirteenth Rule: There is no limit to the time nor energy that many programmers are willing to spend to avoid learning Common Lisp.
  • Burton's Eighteenth Rule: Every Lisp programmer will be tempted to create their own iteration facilty that has neligible new features and immeasurable new flaws when compared to Common Lisp's LOOP.

ASDF groveler
;;;; This ASDF groveler does not use ASDF's own operation framework because
;;;; it does not need the systems to be loaded or compiled. It is possible
;;;; to do some introspection of ASDF systems via the ASDF perform methods,
;;;; but ASDF assumes that the systems will be loaded into the host
;;;; implementation. In other words, the ASDF3 feature expressions will use
;;;; CL:*FEATURES*, but overriding CL:*FEATURES* will result in ASDF
;;;; attempting to load and compile the system being introspected with those
;;;; features leading to disastrous results.
;;;;
;;;; Instead, we walk the dependency/child component graph ourselves and
