You mean the very first time you want to call it and you don't know the exception set yourself by looking at its signature? Put the call in a nothrow scope and compile the module (which is fast in D), the compiler will then complain which exceptions you didn't catch (requires improvement of nothrow analysis [1]).
So to know what exceptions are possible you have to compile the code? I consider that inferior to other solutions such as callee explicitly stating what exceptions it may throw, because then all you have to do is glance at the callee. Also, I think explicitly stating your intent in this manner (by the callee not just the caller) is a good idea, to make sure you are not throwing some exception you didn't mean to throw.
