std.range could publically import std.algorithm and std.math. This should solve the problem without putting min/max/abs and others into global namespace.

Yes, but they are really general functions. IMHO, you shouldn't have to import std.math to do abs() of an integer. It's been a single, trivial asm instruction on just about every CPU ever made.
