    Wow, thank you! I did not try this one! It works and gives the expected output:
    Bareword "hi" not allowed while "strict subs" in use at ./1.pl line 3. Bareword "hello" not allowed while "strict subs" in use at ./1.pl line + 4. Bareword "hola" not allowed while "strict subs" in use at ./1.pl line +5. Execution of ./1.pl aborted due to compilation errors.

      Any time!

      Besides, I did write "should" & "untested". 0:)

    And you think none of us tested this already and we all were too modest to post a code that works???

    The parser needs to see the declaration before it parses the barewords.

    BEGIN-blocks don't change the parsing order, only the runtime order!

    update

    to be precise BEGIN-Block are run at parsing time, but the parsing order doesn't change. see perlmod

      Of course (about everybody being modest:>).

      In any case this did remind me of the reason to generate subs in BEGIN block near the very start of a module.
