Please make another enhancement request for this, so it's not forgotten and we can wait for a separate approval.

This is unreliable. If `fact` is nested inside of a mixin template you won't be able to call the function this way. On another note this has uncovered a new ICE in Issue 9182.

It's also very untidy to have to use mixins and string representation for recursive calls. It's much simpler to use 'return __function(n - 1)'.
