note remiah <p> I also think this is strange. There is no checking for ref($class). I guess something like ... <code> if ( ref($class) ){ my $t = $wanted; $t =~ s/^[+-]//; return bless { sign => $class->{sign}, value => $CALC->_new($t), }, ref($class); } </code> should be in new constructor, doesn't it? </p> 996030 996036
