The default type constraint is Mu, with a default of Any (everything
is of type Mu, and most are of type Any)
You shouldn't be able to change the type constraint of a scalar
container (used for rw variables)
Changing the type of a value, of course makes no sense. (a Str is
always a Str, even when you use it as a number)
Basically no you can't change the type, but you didn't do that anyway.
