I don't think so. I think you just want something like

# Initialize a new Z object for each element of @inits
my @obj_array = map {$z->new($_)} @inits;

or if $z is an object of the desired type rather than a class name,

# Initialize a new object of the same type as $z for each element of @
+inits
my @obj_array = map {ref($z)->new($_)} @inits;
