I'm not sure how it could be construed in any other way than "a =
(b[c]):d()" in that context. Were you supposing that 'b' might be a
function? As far as I recall, functions can only accept a string
literal or a table literal as an argument without requiring
parentheses, so "b t[d]" is already syntactically invalid.
