Actually every programmer will know what if means. If you read LOG(X,Y,Z) you
won't know what this means, until you lookup LOG(X,Y,Z).
Of course LOG() is quite short as
int main(int argc, char**argv) { return run(argc,argv); }
well quite readable but you won't know what happens.
Logging code blocks should be like paragraphs anyway.
