The many things Andrei keeps explaining (teaching) me have changed the way I desire the "ranged integrals" in D. Now I'd like means to implement "good enough" library-defined ranged integrals in D2, instead of just having them built-in.
I think currently D2 offers a good enough syntax to implement ranged integrals in a library. There are some problems, like: http://d.puremagic.com/issues/show_bug.cgi?id=4053 http://d.puremagic.com/issues/show_bug.cgi?id=4331 Another problem is that to implement efficient ranged integrals you need to read the overflow and carry flags of the CPU. To do this efficiently I think you need Asm instructions. But this kills inlining. And if you want to implement a ranged integer then inlining is just necessary, otherwise you a function call every time you want to sum two ranged integers. The LDC compiler faces this problem in two ways, the allow_inline pragma: http://www.dsource.org/projects/ldc/wiki/Docs#allow_inline And "Inline Assembly Expressions": http://www.dsource.org/projects/ldc/wiki/InlineAsmExpressions Is it good and possible to add some similar feature to D2? Is it possible to fix bug 4331? Bye, bearophile
