They gain us compliance with the whims of the people who like barewords
for variable names. You may or may not find that to be a good thing.
I like flexibility.
We also gain a way of differentiating between a "Scalar" which refers
to a "type" which is something else and a lot of very late binding, and
a fixed-size object, an implementation detail that rfc 161 does not address.
These fixed-size "external" objects would not subclass Scalar, and they
could be easily differentiated if they were barewords. From a API point
of view they are crippled scalars.
