What does this mean:

function print(x) print(y) end

With your suggestion, we can't tell unless we know whether it's in an
expression or statement context. This makes code less readable and
error reporting less accurate. Not a good deal to save the occasional
pair of parentheses.

So what does 'f -123' mean?

What does 'print(x) print(y)' mean?

print(x); print(y)?
print(x)(print)(y)?
print(x)(print(y))?

Not good...
