bless
bless - create an object 
bless REF,CLASSNAME
bless REF
This function tells the referenced object (passed as 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, since 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.
