### Enumeration (enum) in Perl6

Perl6 has enum. Now I have acquired a little bit of the Ada mindset, so I expected something similar. But Perl6 isn’t Ada, of course, hence I was disappointed. Should I retune my expectations taking into account this fact?

Yes, but also no. Because Perl6 enumeration doesn’t feel completely right.

### Snippet/ Prolog in the Java documentation

Just spotted this:
The type checker enforces type rules that are specified by means of Prolog clauses.
from here.

### Dynamic dispatching reloaded

In previous posts I was exploring a feature I am interested in, and which I have called in many different ways — here I will call it dynamic dispatching.

The previous articles:

Conclusion of those posts: out of the box only Perl6 has it.

The story went on like this: I stirred the net for a solution in C++. And I obtained it.

### Nested functions

Some languages allow nested functions (or procedures, or subroutines, or whatever you prefer to call them), others don't.

I think those can be useful and I wonder why they aren't embraced by all living programming languages.

### Changing input validation in an established API

Let's suppose that your server S exposes an API and that this API is used by many clients, or maybe just one — it doesn't really matter.

Let's focus on a client only, let's call it C. Documents were exchanged between S and C, so to agree on the interface.

After that, tests were done and none raised issues or, if they did, they were fixed.

The tests stated that S and C can talk, that they can understand each other, that C calls S correctly, that S acts properly according to the request, that C parses server's answer correctly, and so on.

Everything works fine, or mostly fine, since the beginning.

### This is google

I am not going to do anything about it. If there are interesting comments, they'll be lost. Hopefully I haven't relied on comments very much — thankfully no one, or few, cared to comment! There are maybe a couple of exceptions in this very same blog. As already written, I am not going to do anything about those, sorry.

But remember: Google can take away from you everything it's given before, and you haven't a say (of course). Hence don't forget that things you can touch in the world are, and always will be, better than anything digital.

### “Dynamic overloading” in other languages (not C++)

In a previous post I've imagined that future C++ could dynamically dispatch a call to a proper function/method according to the derived types of its arguments — that is, dynamic overloading, whereas notoriously in C++ overloading is a compile time feature.

Now the question is: what about other languages?
