=item Try to design the new module to be easy to extend and reuse.
-Always use B<-w>.
+Try to C<use warnings;> (or C<use warnings qw(...);>).
+Remember that you can add C<no warnings qw(...);> to individual blocks
+of code that need less warnings.
Use blessed references. Use the two argument form of bless to bless
into the class name given as the first parameter of the constructor,
e.g.,:
sub new {
- my $class = shift;
- return bless {}, $class;
+ my $class = shift;
+ return bless {}, $class;
}
or even this if you'd like it to be used as either a static
or a virtual method.
sub new {
- my $self = shift;
- my $class = ref($self) || $self;
- return bless {}, $class;
+ my $self = shift;
+ my $class = ref($self) || $self;
+ return bless {}, $class;
}
Pass arrays as references so more parameters can be added later
difficult for multiple other packages to use yours. Keep state
information in objects.
