Subject: [PATCH] Sometimes at php7 uniqid() return same result as their
 previous call. Here generates few equal labels wich makes error on eval. Does
 not know why uniqid() return same values but this is fact and my construction
 is more correct than previous. No need to call label id generation and use
 dirty goto :')
