$ ./perl -we '$a = @​$a > 0'
Use of uninitialized value $a in array dereference at -e line 1.
Use of uninitialized value $a in numeric gt (>) at -e line 1.

That second warning is wrong. It should be

Use of uninitialized value in numeric gt (>) at -e line 1.

Hash derefence has the same error in the warning for numeric gt. Scalar
dereference does not.
