I thought that many places in stdlib could be made faster by this (bool is used a lot), maybe this is a major speedup.

I doubt that there are many places in the stdlib where the call to bool is the bottleneck, and a micro-optimization of avoiding the function call would make it a "major speedup". If you profile the stdlib modules, do you find any where calls to bool make up a major part of the run time cost? -- Steve
