In modern versions of Perl (I use 5.12) you can use the state keyword.

From the docs:

state declares a lexically scoped variable, just like my does. However, those variables will never be reinitialized, contrary to lexical variables that are reinitialized each time their enclosing block is entered. state variables are enabled only when the use feature "state" pragma is in effect.

But take care: even if you leave the loop entirely and re-enter it later, the state variable will still have maintained its last value!

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
