syntax error at example.pl line 12, near "my "
Global symbol "%snacks" requires explicit package name (did you forget to declare "my %snacks"?) at example.pl line 12.
Global symbol "%snacks" requires explicit package name (did you forget to declare "my %snacks"?) at example.pl line 17.
Execution of example.pl aborted due to compilation errors (#1)
    (F) Probably means you had a syntax error.  Common reasons include:

        A keyword is misspelled.
        A semicolon is missing.
        A comma is missing.
        An opening or closing parenthesis is missing.
        An opening or closing brace is missing.
        A closing quote is missing.

    Often there will be another error message associated with the syntax
    error giving more information.  (Sometimes it helps to turn on -w.)
    The error message itself often tells you where it was in the line when
    it decided to give up.  Sometimes the actual error is several tokens
    before this, because Perl is good at understanding random input.
    Occasionally the line number may be misleading, and once in a blue moon
    the only way to figure out what's triggering the error is to call
    perl -c repeatedly, chopping away half the program each time to see
    if the error went away.  Sort of the cybernetic version of 20 questions.
