in thread Iterating over *any* thing in Perl
Except that it's not. An object is nothing more than a blessed reference, not data structure. Observe:use anal::retentive;
Now you know I like to quote ;) from perldoc -f blessmy %foo = (1,2,3,4); bless %boo,'bar'; __END__ Can't bless non-reference value at - line 2.
bless REF,CLASSNAME
bless REF
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 the function
doing the blessing might be inherited by a derived class. See
the perltoot manpage and the perlobj manpage for more about the
blessing (and blessings) of objects.
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, so to prevent confusion, you may wish to avoid such
package names as well. Make sure that CLASSNAME is a true value.
See the section on "Perl Modules" in the perlmod manpage.
update: hmm, it's a weird thing, the datastructure is "blessed", but only the reference knows, weird
