There is at least this (weird) one:
split; ## @_ = split(' ', $_, 0);
And some more related to yours:
for (;<FILE>;) { ; } ## [ exactly the same as above ]
print while readline; ## ... while defined($_ = readline *ARGV)
print while glob; ## ... while defined($_ = glob $_)
The last one is kind of strange...
