Yeah, but what is the intention of all other code that uses: 
my $var if COND;

[download]
? Either the if COND is redundant, because it's always true, or it maybe false and you have the same issue. Also, 
my $var = 0 if 0;

[download]
creates a "state" variable, yet there's no warning.

Now, I'm usually not a fan of adding a warning for every little thing, but if there's a warning, it shouldn't be inconsistent on when it warns and when it doesn't.
