in reply to execute a string as a function

And don't call your subroutines with the '&' added to its name. It has certain side-effects you do not need.

CountZero

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

    I'll bite.

    What side-effects?

      perlsub
        &NAME(LIST);   # Circumvent prototypes.
        &NAME;         # Makes current @_ visible to called subroutine.
      
      
        cute, where are the sideffects?
        &unpack_c( $lines[$_] ) ; VERSUS unpack_c( $lines[$_] ) ;
