It's like the old joke: "Doc, it hurts when I do this." Doctor: 
"Don't do that!"

I need both constant and mutable BigInts.

I don't want to convert a constant value to mutable, I just want 
a mutable copy. The cast was just a way to make a mutable copy 
but it's broken now.

Other types have a .dup property which returns a mutable copy, 
but BigInt doesn't.
