在Perl中,在属性中保留对Catalyst的$c的引用会导致内存泄漏吗？

package My::Controller;
extends 'Catalyst::Controller';

sub handler :Path :Args(0) :Location( some/url )
    my ($self,$c) = @_;

    $self->do_something_with_arguments($c);
    $self->make_a_decision($c);
    $self->another_method($c);
}

然后我想. o(为什么一直传递$c？),我改为：

package My::Controller;
extends 'Catalyst::Controller';

has c => (is => "rw",isa => "Catalyst");

sub handler :Path :Args(0) :Location( some/url )
    my ($self,$c) = @_;
    $self->c($c);

    $self->do_something_with_arguments;
    $self->make_a_decision;
    $self->another_method;
}

处理程序只有一个入口点,因此$self-> c将始终正确设置.

我的同事说,如果这就是Catalyst的意思,那么,每个人都会这样使用它.他们担心这样做会导致内存泄漏,因为在请求结束后对$c的引用会持续存在.真的吗？
