I am trying to put an option into my perlscripts which
allows for a debugging switch which, when submitted to
the script, prints out debugging messages.

Problem is that I get
(a) a warning because I redefine a subroutine, and
(b) the debugging information is printed no matter if the switch is submitted or not.

Any dice, anyone???

# set debugging switch to default (off)
use constant DEBUGGING => 0;

# loop foreach argument
foreach $_ (@ARGV)
{
    # is argument '-d' or '-D'?
    if ( /^-d$/i )
    {
        # yup. use 'no warnings;' to suppress 'subroutine redefined' w
+arning

        no warnings;

        # change debugging switch to ON
        use constant DEBUGGING => 1;
    }
}

...

print "FUNCTION_NAME: Debugging Information\n" if DEBUGGING;
