Is there a GCC extension for implict return values?
class SomeClass {
public:
    static int AdjustValue(float input);
    static int DoSomethingWithAdjustedValue(int adjustedInput);
    static int DoSomethingWithNormalValue(float input) {
        DoSomethingWithAdjustedValue(AdjustValue(input);}
};

> g++ xa1.cpp -Wall
