One of these types are the types of functions. But still, using ``var`` it is possible to have local variables of these types:: - - contract FunctionSelector { - function select(bool useB, uint x) returns (uint z) { - var f = a; - if (useB) f = b; - return f(x); - } - - function a(uint x) returns (uint z) { - return x * x; - } - - function b(uint x) returns (uint z) { - return 2 * x; - } - } - -Calling ``select(false, x)`` will compute ``x * x`` and ``select(true, x)`` will compute ``2 * x``. - .. index:: optimizer, common subexpression elimination, constant propagation ************************* |
