Lets see what I actually said:

Did I say empty pattern? No... so you can't assign me
those wrongs. Besides, this works fine:
local $_ = "Hi There";
if (/Hi/) {
print join "-", (split //);
}
which is the opposite of what you implied. The reason
is that for // the default regex is the previous
expression... but for split the default is a single
space character. Split behaves differently from a
normal regex function.
