However, if array int key size is 32bit, 64bit value would never fit. I agree Rasmus's argument about string offset. If anyone would like to deal with extremely large data, they should use stream or like. It just wouldn't work well without it now. Regardless of this RFC acceptance or not, it's nice if all of these limitations are documented in the manual under single section. Perhaps, new appendix? Regards, -- Yasuo Ohgaki yohgaki@ohgaki.net
