Between December 2007 and July of 2008 we carried on a series of exchanges
regarding the addition of unsigned types to the X10 language. On rereading
the exchange, it seemed that we were disposed in favour of adding this
feature. However, on reviewing the 1.7 specification, there does not appear
to be any reference to unsigned integers, nor does the 1.7.x version of the
compiler seem to support them. Will unsigned types be added to the language?
Also, in the same series of discussions, we noted a need for 64bit array
indices to accommodate large Rails. The discussion seemed to finalize with
"yes, but we need to think about how to do it right". Will 64 bit array
indices be added to the language?

Has any thought been directed toward the addition of 32 bit and 64 bit
unsigned integer types? (unsigned int, unsigned long)
