in reply to my and local differences

Always use my unless you need to use local.

Time when you need to use local include:

  • On "punctuation" variables (for example, $_)
  • When you want to access the localized variable in a subroutine that you call from inside that scope.

    Instead of mentioning the punctuation variables, I usually tell people "use local whenever you want to mask a global variable with a localized value". The "punctuation variables" are examples of global variables that you might want to change the values of in a particular scope.
