cab595ec0f bigint pure 
the only exception is toString as it takes a delegate and this makes
things more tricky

47c7ade97e Throw error upon division by zero. 
Instead of trying to trigger an integer divide by zero, which seems to
get "optimized" out by the compiler.

302323559a Revert "not really pure" 
This reverts commit 4f28db6ffb.

Since Walter put weakly pure back in, these changes need to be undone.

9110377e42 5928 Bigint modulo problem

9ecf947290 5568 A problem with BigInt modulus 
This is quite subtle. The recursive division algorithm has a possibility of one
bit of overflow in the second recursive call, in cases where the top quarter of
the dividend is identical to the top half of the divisor.
The description of the recursive division algorithm in "Modern Computer
Arithmetic" 0.5.9 is rather vague about this (which is why I missed it
originally, though the test case does cause assert failure in biguint).
Unfortunately it requires fairly substantial changes to the function, which
makes the algorithm a lot less elegant. But I have managed to implement it
without any change to the basic division algorithm (which is very fast).
