I don't understand.  You're comparing this:

(let ((thing (replace-regexp-in-string " +" " " thing)))
  (fmt "This is %[.2f]{thing}.2f"))

to this:

(fmt "This is %{thing}.2f"
     :thing (replace-regexp-in-string " +" " " thing))

right?

Admittedly the form below doesn't rebind "thing", but it now has ":thing" and "thing" meaning different things.

Cheers,
Clément.
