Lionello Lunesu:
Have a look at the branch: https://github.com/lionello/dmd/compare/if-else-range
The need for this D improvement is sufficiently common, a just appeared question:
http://forum.dlang.org/thread/[email protected]Lionello needs some cheering & support to create the patch that implements the value range propagation for if-else. Exposing the range and implementing value range propagation for if-else are sufficiently distinct needs.
