Exegesis 6 (Perl 6 Subroutines) Released

chromatic writes "Perl.com has just published Damian Conway's Exegesis 6 which gives practical examples demonstrating how to use the new subroutine and method semantics in Perl 6. This is the companion to Larry Wall's Apocalypse 6 which discussed the changes planned for subroutines in Perl 6."

There's a long way to go

I mean, whitespace hasn't even been made meaningful yet.

Where's $\space and $\tab ?

Oh lord, variable names/function calls with whitespace.

That would truly make perl executable line noise.

Thank God Damian isn't working on the Apocalypses...

Perl floats *all* boats

That's the point of Perl. If you don't want to use the verbosity of:

sub Fahrenheit_to_Kelvin (Num $temp is rw) {

You don't have to! You could just as well use:

sub f2k ($temp) {

Perl will allow either. It's your choice. You can do the quick one-off-hack-it-up-at-3am-after-two-large-pots-of- coffee, and you can have a large programming project that must be maintained for years to come.

You have the choice. Pick whichever method fits the task at hand.

The problem is that it'll be the one-off-hack that'll have to be maintained for years to come, while the large programming project will just sit and collect dust in a closet.

This guy is not trolling

Erm, yes I was...

There's more than one way to do it?

[MoxFulder]

Perhaps the Perl motto should be changed from TMTOWTDI to TAMODVPCWDSSAAMSTWDI:

"There's a multitude of different visually pleasing constructions with deceptively subtle syntax and auto-magical semantics that will do it."

Okay, I love Perl 5... Perl 6 looks really cool but overwhelming. I'm glad they're adding the options for stricter type-checking and such, but remembering the syntactic shortcuts is gonna be even harder. I don't even want to know what the parser code looks like...

What's wrong whacking a cockroach with a baseball bat? Here in Houston, carrying a baseball bat as protection against cockroaches is common sense, plain and simple.

Yes, that's great! I'd much rather spend large portions of my day worrying about manual type conversions, instead of actually writing the business logic for my application.

Anyway, you are totally wrong, every object in C# is derived from 'object'. Same as VB.NET. Same as Managed C++

I think you're talking about the object model of the .Net runtime, and that's fine, but .Net runtime is not a language, and its objects are not language primatives.

To give an example of C++, and then discuss what is effectively an RPC-based library's object model is way, way beyond the scope of the original conversation.

Like I said before, this is not a unique feature to one, or even a dozen toolkits, languages, etc in the last 10 years. You're not citing something that originated with the example that you are citing. I was responding to an assertion of yours that you seem not to really be talking about any more, so I'm going to drop this thread.
