I think the above is clearly better than `preformat` under one
condition: make it a function rather than a macro.
The downside (other than performance, tho that can be compounded by
a compiler-macro) is that

    (fmt "This is %{thing}.2f")

won't work any more, you'll need

    (fmt "This is %{thing}.2f" :thing thing)

instead.
