I'm afraid so.  As far as I know the only way to fix this is to add a
hard dependency on numbers to fmt.  This may not be desirable depending
on what you're using fmt for.

This is a result of the second class treatment that extended numbers get,
and will be fixed in CHICKEN 5, due to integration of the full numeric
tower into core.

Note this is in contrast to how 'numbers' used to work, where

loading it overloaded all numeric operations globally.  The fmt

documentation still reflects this previous behavior.
