Ruby would find it out because of the leading "(" or that would be
what I and apparently Sky Yin expect.

This works:
irb(main):001:0> (1
irb(main):002:1> )
=> 1

This too:
irb(main):003:0> begin (1
irb(main):004:2> ) end
=> 1

But I think I understand why it works this way. In Yin's example:

(1*2
+1)

is interpreted just like
(1*2;
+1)

what would not happen if he had written
(1*2+
1)

which gives a proper answer.

Kind regards,
Adriano.
