I've only seen small amounts of Ruby code on the net. The only way I can make some sense of that is if it gets analyzed as follows, using parentheses for calls: a + b => 7 # a() + b => a(4) + b => 4 + 2 + 1 a+b => 7 # a() + b a+ b => 7 # a() + b a +b => 3 # a(+b) => a(b) => a(1) = 1 + 2 I'm not quite fond of such surprise in programming language syntax. -- https://mail.python.org/mailman/listinfo/python-list
