in reply to Perl OOP

As others have now said, the Perl5 implementation of objects is, shall we say, “grafted onto” the language, not designed into it.   Essentially, it revolves around the verb, bless, which associates a package with a memory-variable so that the -> nomenclature can be used against it.   Other packages, specifically Moose and its brethren, provide further “wrappers” to make things a little bit easier, but all of these are written in Perl5 and so cannot entirely escape nor make up for its lack of built-in class features a la Java or C#.

The Perl6 language, which is really an entirely different beast, did implement, within its core language, some (but not all) of the features that you are used to from your prior-language experience.

Despite its simplicity, the Perl5 object implementation is efficient, even with Moose.   But, at least at first, you will perhaps be caught off-guard by the general lack of a compile-time, and the error-tests which customarily occur at that time.   Perl is not a “strongly typed” language:   in fact, it is typeless.   Perl will compile and run scripts and catch (or, maybe not catch) errors at runtime which you might be accustomed to have been trapped before the program ever started to run.   It is a “DWIM = Do What I Mean™” language that may or may not actually know what you mean.   Therefore, you will probably experience a few “impedance mismatch” moments as you get the hang of things.
