It isn't changing anything.
You've still got a box ('container') that can only hold something 'Real'.
You just happen to have a value in that box that is a 'Rat'.
It is perfectly fine to put a Rat value in a Real box, because a Rat
is also a Real (does the 'Real' role).
You can still stick some other Real in the box, and you still can't
stick anything that isn't a Real in the box.

I would add on top of Curt's explanation. Try assigning Nil to $x and
then ask for its type. You'll get your Real back!
I am see it but I am not seeing your point:
$ p6 'my Real $x= Nil; dd $x;'
Real $x = Real
$ p6 'my Real $x= Nil; $x = 3.1415; dd $x;'
Rat $x = 3.1415
Why is it changing the type on the fly after
I defined it?
