This is probably because Javascript has 'implicit semi-colons'. The
parser rule is that if you see a line break where a semi would be
accepted, pretend you saw a semi. Unfortunately that makes:
return
foo
Parse as:
return;
foo;
And your function returns no value and `foo` becomes unreachable code.
(In JS2 they have fixed this by not permitting an implicit semi
between return and an expression.)
