This is a very interesting question.

Take care that if you cross the memory / storage boundary, independent copies will be created:: contract C { - uint[20] x; + uint[20] x; - function f() { - g(x); - h(x); - } + function f() { + g(x); + h(x); + } - function g(uint[20] y) { - y[2] = 3; - } + function g(uint[20] y) { + y[2] = 3; + } - function h(uint[20] storage y) { - y[3] = 4; - } - } + function h(uint[20] storage y) { + y[3] = 4; + } + } The call to `g(x)` will not have an effect on `x` because it needs to create an independent copy of the storage value in memory |
