It really doesn't matter what you call it. I tend to give it a name in context with the name of the module. For instance, I am writing a wrapper around DBI.pm to handle all my database calls and I call the instantiating subroutine connect.

What is important is that you have a sub that blesses a hash. Objects are really hash references and blessing allows them to call subs from their module as well as the information stored within them.

To be specific, you need:

#...
my $self = bless {};
#...
return $self;
#

Note that 'return $self' is not required if bless is on the last line of your code and you don't assign the bless to a scalar.

Hope that helps!
