I don't really get your remark about use strict;.

use strict 'vars'; let's the programmer know that a variable they used doesn't exist. The programmer uses the pragma because they wish to know that (i.e. they care to know that).

Therefore, it's a counterexample to your claims that existence doesn't matter except "in the few edge cases where you can poke into the underlaying implementation" is false.

And do get your capitalization right when it matters.

I did. perl "compiles and runs: print $foo;", not "Perl (language!)".
