It makes for very inconsistent results. I personally think that until enforce doesn't prevent inlining it should not be used anywhere in ranges since much of the range concept's charter is for inlining performance advantages.

And ranges will likely never stop affecting inlining.  It's not just a 
DMD optimizer sucking issue.  It's also the amount of code an enforce() 
call generates.  Read the disassembly to one and you'll see what I'm 
talking about.
