I'm not quite sure what you think the uncommenting of
is going to show. It's certainly not
going to forbid the use of symbolic references! Because
that's something that happens at run time, and the code
above doesn't compile when turning on strict. You can fix
this by using $::ref
Then you will a "useful" message about using scalar references
when turning on strict.
However, the example doesn't impress me at all. Without strict, there's nothing dangerous or even strange happening.
In fact, Perl is quite doing what people would expect.
You'd have to come up with a better example if you want
people to get hooked to use strict - this example
will just get them hooked to using symbolic references.
