 as you say, they're incredibly common to use.  Not sure if people would
 object to these symbols being an implicit part of the namespace of every
 module though.

 Agreed.  These are things that are so often used and so basic that even the
 overhead of having to remember to import something to use them is sometimes too
 much.  As far as namespace pollution, what reasonable person would ever name
 something max(), min() or abs() if it doesn't do what the standard max(), min()
 and abs() functions in Phobos do?


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.
