Is there a reason why std.algorithm doesn't provide a lazy range 
implementation of replace()?

I'm aware this isn't difficult to express using `map` like, for 
instance,

auto replace(S, F, T)(S, F from, T to)
{
     return s.map!(a => a == from ? to : a);
}

but I prefer syntactic sugars.

While at it we could make use of variadics to enable syntax such 
as

     assert(equal("do_it".replace('_', ' ',
                                  'd', 'g',
                                  'i', 't',
                                  't', 'o',
            "go to");

along with optional predicate (as usual).

What do you say?

Sample implementation at

for one replacement pair.
