$gaz contains the second line. Otherwise this:
while (<'filename'>){print;};
won't work. This gets a little hairy, I admit.

Of course. Stick any old list there.

This is an implemenation detail. On the other hand, I was hoping that
it would be easy for a human parser. Perhaps it only takes some getting
used to. Like the first time I saw something like:
for ($foo){
/pattern/ && next;
print join ' ', /pattern_with_groups/;
};
To my eye angle brackets signify input.
