Off the top of my head:

foo(bar)
("string literal"):baz()

Could be useful in either interpretation (assuming you've given the
string's metatable something useful to call as a statement)

Since you can't use string literals directly with :, they need to be
in parentheses (at least in 5.1, don't know if this has changed)
