Re: unsigned int optimizations?

Integers which can fit in an INT_TYPE are stored as such, not as bignums.

yes, but there is a difference between signed and unsigned int. an integer larger than 2147483648 and smaller than 4294967296 does not fit into INT_TYPE

but it would very well fit into an unsigned int type.

if pike handles an array of a few thousand of these the use of bignum vs unsigned int type could make a difference.

(In strings smaller integer types are used as appropriate, because there it actually saves memory.)

right, i was thinking of something like array(int(0..255)) because this could be saved as a string.
