Hi,

I have a little question. I use constants in my script for debug messages, but I wondered if they need execution time. As I unstood the Perl Optimizer discards code that is never reached, but there seems to be "Optimization Levels" (right???). So does the following print in the code bother my script while executing? Would it make any difference if I delete those lines? 
package Test;

use constant DEBUG => 0;# There is also one in the main package, for t
+urning all on


sub new {
print "Test->new(@_)" if (DEBUG || main::DEBUG);

...
}

Humble,

Andre
