Perl OOP and reference

Perl can do OOP for sure. I reviewed relevant material for recent work. Use "Package" to define a class. What's interesting is the use of "bless" keyword. An object is used in the syntax of a C++ object, say you use "->" to retrieve its member variable or function.

The use of reference facilitates a lot of programming features. In Perl using a back slash "\" in front of a variable (scalar, array or hash) turns it into a reference. This can be passed to subroutines, to be used recursively etc. To cast it back and refer to the object, use $/@{}/%{} for scalar/array/hash respectively.
