Since DDT (Eclipse plugin) uses Dub, I am trying to convert the DWT
build instructions into Dub. Here is my current attempt:

Never mind. someString is actually the result of stdin.byLine(), which
returns a char[], not a string. I didn't notice this until just now.
.idup fixes this just fine

data.put(someString);

typeid() is a runtime function. I think it will be costly every time
toHash is called. The function pointer can be initialized once.

I have a class which contains an int[] and some other stuff. I want to
use my class as the key for an AA, so I am overriding toHash(). But the
int[] is the only part which should produce the hash code. I know that
int[].toHash() is defined somehow, because I can put int[] directly into

Hmm...throwing an exception is a well-defined behavior, but is

I didn't realize this was possible... I figured it was equivalent to

That's not true. They can also come from IUnknown or a C++ interface.
Ok, that's a good reason!
