The following are expected failures:
;; - Under CLISP, highlighting of macro sub-forms fails because our
;; pretty-printer dispatch table hacking causes infinite recursion:
;; see comment in swank-macrostep.lisp
;; - COLLECT-MACRO-FORMS does not catch compiler macros under CLISP
;; and ABCL
;; - Under CCL and ECL, compiler macro calls returned by
;; COLLECT-MACRO-FORMS are not EQ to the original form, and so are
;; not detected by the tracking pretty-printer mechanism. This
;; could be fixed by adding :TEST #'EQUAL to the POSITION call
;; within MAKE-TRACKING-PPRINT-DISPATCH, at the cost of introducing
;; false positives.
;; ECL has two other issues:
;; - it currently lacks a working SLIME defimplementation for
;; MACROEXPAND-ALL (Github issue #157), without which none of the
;; expand-in-context stuff works.
;; - the environments consed up by its WALKER:MACROEXPAND-ALL
;; function are slightly broken, and do not work when passed to
;; MACROEXPAND-1 unless fixed up via
