No, this is not an opportunity for everyone to evaluate my behavior. It's my's behavior that is under the microscope here.

All bad jokes aside, I was playing around with the trinary operator and was trying to do what I guess you could dynamic variable declaration. For what purpose? I don't know. I just wanted to see if I could do it.

Basically what I was trying to do was: 

((shift @ARGV) ? $foo : $bar) = "Hello";

So whether or not there is an argument to the script would decide which variable, $foo or $bar, would be declared.

It works fine as is. But if I try to declare with my while using strict, everything falls apart and I get an error. 

use strict;

my ((shift @ARGV) ? $foo : $bar) = "Hello";

# Can't declare null operation in "my" at trinary.pl...

So I suppose a null operation is one in which no value is returned, which makes sense because why would you use my to declare nothing.

So I'm wondering why this is considered a null operation. The trinary should return one value or the other, in the case either $foo or $bar. The only thing I could think of is that b/c strict is in effect, $foo and $bar do not are evaluated before being declared with my and so technically don't exist. But then I wondered why that didn't through a Global symbol error. And besides that, my behaves the same way and throws the same error whether I use strict or not.

Anyway, I'm at a loss. Any ideas?
