in thread scoping inside the loop

Thanks LanX.Understood but in second case which is a working condition $i's scope is in outer loop but how it got tucked in to inside loop.My understanding is if my is before a variable it's existence is strictly with in that boundary. In case 2 my is associated with $i so i think it only resides outside or where it is defined but i am confused how it got transported to loop.

    No, up to the point that you declare an inner $i with my the outer one is used.

    No inner my $i means the outer one is everywhere available.

    These are universal rules for lexical variables in almost any language!

    Have a look at the scoping-article I linked.
