Found in the bowels of op.c (while debugging a weird perl bug):
/* perl4's way of mixing documentation and code
(before the invention of POD) was based on a
trick to mix nroff and perl code. The trick was
built upon these three nroff macros being used in
void context. The pink camel has the details in
the script wrapman near page 319. */
const char * const maybe_macro = SvPVX_const(sv);
if (strnEQ(maybe_macro, "di", 2) ||
strnEQ(maybe_macro, "ds", 2) ||
strnEQ(maybe_macro, "ig", 2))
useless = NULL;
else {
