Looks like std.conv.to always allocates behind the scenes. It's a

the returned string is immediately processed and discarded in my XML

to!string(7, outputRange)?

I know about Steven's proposal but it applies only to user types not
primitives. Either way std.conv.to would need a buffered output range
as integers are written from the right. Any chance for an abstraction
analogous to buffered input ranges discussed recently?
Generally I found it more difficult to define a solid output buffer
abstraction. This is a great motivating example though.
To my surprise, an API of the same form seems to be what the doctor
prescribed.
I meant "of the same form as buffered input ranges". The primitives are
similar: expose a buffer, allow it to grow, and discard it progressively.
