Custom literals:

Hm, yes. That is useful.
Also, in these examples the function call actually looks like a literal prefix.
If such convention is followed, it really is obvious what the code does.

Fun fact:

-- Error
function s(v) return v end
-- "2A"
So… I guess it does not make much sense to force use of parentheses for method calls only around "primitive" string literals.

also give this a try:

function x(x) print("xing") return x end
("foo"):gsub(".*", print)
"bar":gsub(".*", print)
