bless - create an object
This function tells the thingy referenced by
REF that it is now an object in the
CLASSNAME package--or the current package if no
CLASSNAME is specified, which is often the case. It returns the reference for convenience, because a
bless() is often the last thing in a constructor. Always use the two-argument version if the function doing the blessing might be inherited by a derived class. See
the perlobj manpage for more about the blessing (and blessings) of objects.
