a) a "var" parameter is considered as initialising a variable (although it also expects input to be initialised already)
b) "Uninitialised" hints/warnings are only given once per variable (even regardless of whether the warning/hint is printed or not, as the state of the variable in the compiler will be changed so that it won't be printed anymore).
