Thanks, that was what I thought, but there is no return in the Execute() sub, so it looks like it's useless code.

    No necessarily useless... the last line of a subroutine becomes its return value if none is specified explicitly... so: <CODE> sub foo { 1; } #and sub foo2 { return 1; } both return 1

    In Perl, the value of last evaluated statement is returned in a subroutine - the return token is optional, but you shouldn't abuse this (too much).

      In Perl, the value of last evaluated statement is returned in a subroutine
      expression, not statement. You can't evaluate a statement.
