Hello,
Walter and I were talking about eliminating the surreptitious
allocations in buildPath:

We'd need to keep the existing version working, so we're
looking at adding one or more new overloads. We're looking at
giving the user the option to control any needed memory
allocation (or even arrange things such that there's no memory
allocated at all).
It's a generous design space, so although we have a couple of
ideas let's hear others first.
Thanks,
Andrei
Use an output range. It's the generic D approach, and what we
already do for the string functions such as std.string.translate:
http://dlang.org/phobos/std_string.html#.translate
(look down for the output range overloads).
Anything "allocator" related should be carried by the output
range itself. The function itself should not care nor know about
any of that.
