But isn't this always the case when you're dealing with statements that take lists as arguments?

# Ooops! print join ",", @foo, "\n"; # Ooops! print grep /o/, @foo, "Hello world!\n"; # Ooops! print table{ map { tr(td($_->[0]), td($_->[1])) } @foo, ...

My rule of thumb is, if one of these statements is followed by anything besides its argument, then parenthesize that statement's entire argument list.

# De-oopsed. print join(",", @foo), "\n"; print grep(/o/, @foo), "Hello world!\n"; print table{ map({ tr(td($_->[0]), td($_->[1])) } @foo), ...
