[Summary:  You can put values into $x that are explicitly numeric or
explicitly strings, while the Camel says you can't declare a scalar to
be a particular type]

One suspects that your example simply goes to prove the point the Camel
is actually trying to make:  the scalar "$x" cannot be pre-defined to
only hold a particular type of value.
