How do you implement BigInt's constructor without being able to throw an
exception?
I presume you mean how can it work without allocating memory. In D, a
memory allocation failure is generally not a recoverable exception, it's a
fatal exception.
A better example would be one that attempted to open a file in the
constructor.
I think he meant that passing it something like "Hello, Fred." should be
disallowed.
Yes, that. I don't see another way rather than throwing an exception. Or
maybe just do like ruby, when you do "hello".to_i it gives you zero but
then you have to check it later.
I don't like factory methods like BigInt.fromString. If I want to create
a BigInt from a string I should use the constructor, why not?
