Re^2: Using Number Ranges in a Dispatch Table

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),
        ...
