On: In Java 3 = 12

Things to consider here are:

- operator precedence

- implicit type casting

- how operator+ is defined per each type (e.g: numbers add, strings concatenate)

[Seol → partycoder]

The interesting thing is that the "obvious correct" behaviour would require the precedence of the + operator to depend on the types of the operands - which is obviously impossible if it's done at the parse stage...
