All of those questions will be addressed by user requests.
As for the $errstr and errstr() stuff ... get rid of $errstr and make errstr() a class method. So, of the form:
sub errstr {
my $self = shift;
return $self->{errstr} if Scalar::Util::blessed $self;
return $errstr;
}
That allows for the possibility of multiple objects.
As for new() failure, the meme is this:
my $obj = CLASS->new( ... ) or die CLASS->errstr;
My criteria for good software:
- Does it work?
- Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
