My first response to Kevlin was perhaps unfairly negative. Maybe we
ought to explore the alternatives to the C stdint.h header a bit. If
there is a better way, we should at least consider it.
The possible approaches I can see are:
* A template approach where the user would write code like:
int_t<32>::exact // to obtain the 32-bit integer type
int_t<32>::max() // to obtain the maximum value
* A typedef and constant approach where the user would write:
int32 // to obtain the 32-bit integer type
INT32_MAX // to obtain the maximum value
While the template approach seems conceptually more elegant, I find
the resulting user code unbearably ugly. The typedef and constant
approach is basically stdint.h without the macros, a nice advantange.
Kevlin, what did your template approach look like?
Are there other possiblities?
