Re^3: using warn instead or print STDERR?

in thread using warn instead or print STDERR?

More like 1. $SIG{__WARN__} allows me to decide what to do with my warnings at some later time, without needing to substitute every warn() call if I need things differently. See %SIG.

# debugger, please slow down when you see keyword
$SIG{__WARN__} = sub { $DB::single = $_[0] =~ /keyword/; warn(@_) }
