This function tells the thingy referenced by REF that it is now an object
in the CLASSNAME package. If CLASSNAME is omitted, the current package
is used. Because a
bless is often the last thing in a constructor,
it returns the reference for convenience. Always use the two-argument
version if a derived class might inherit the function doing the blessing.
See "Tom's object-oriented tutorial for perl" (perltoot) in Perl Tutorials and 16 for more about the blessing (and blessings)
Consider always blessing objects in CLASSNAMEs that are mixed case. Namespaces with all lowercase names are considered reserved for Perl pragmata. Builtin types have all uppercase names. To prevent confusion, you may wish to avoid such package names as well. Make sure that CLASSNAME is a true value.
See "Perl Modules" (perlmod) in the Perl Library Reference Manual (Volume 2).
