And conversely, sometimes the compiler will have a hard
time figuring out which one you want it to pick!
I had an experience in Java recently where a library
author had provided two overloads of a function, that
at first sight could be disambiguated by argument types.
But for a certain combination of types it was
ambiguous, and I was unlucky enough to want to use that
particular combination, and the compiler insisted on
picking the wrong one. As far as I could see, it was
*impossible* to call the other overload with those
I ended up resorting to copying the whole function and
giving it another name, just so I could get it called.
Function overloading: Just say no.
