But maybe it will act as a bit of a visual deterrent. --- diff --git a/src/compiler/generic/early-objdef.lisp b/src/compiler/generic/early-objdef.lisp index c99e7a8..2b1cff0 100644 --- a/src/compiler/generic/early-objdef.lisp +++ b/src/compiler/generic/early-objdef.lisp @@ -11,12 +11,13 @@ (in-package "SB!VM") -;;; FIXME: It's clever using :SUFFIX -TYPE for these things, but it's -;;; a pain for people just learning to find their way around the code -;;; who want to use lexical search to figure out where things like -;;; EVEN-FIXNUM-LOWTAG are defined.
