What's the best way to find out which exceptions may be thrown ?

Note that this is impossible in general due to the nature of 
classes.
A function could at runtime find the latest trending hashtag on 
twitter, name a class after it that derives from Exception, 
invoke the compiler to generate a shared library that throws an 
exception with that class, load that library, and call the newly 
loaded function that throws the newly created exception class.

Obviously there's no way of knowing this class at compile time.
