No no, I think you found the language flaw.

@Kecessa no you missed my point. You change the behaviour of the producer, not the consumer.

@Kecessa @grue knowing that the source will be published discourages bad actors from putting crap into the program in the first place.

And if they do it anyway, other people can come along and repackage it without the bad bits, like vscodium.

@eveninghere @ruffsl that claim's correct. But so far it doesn't have great performance on a single core.

I believe that the trick is not to show the developers the bill.

Let the developers all tell each other "it's cheap because you don't have to buy the servers; you only pay for what you use!"

Only managers see the real price.

@armchair_progamer

Awful naming. Forgetting the fortune 500 company you're already thinking of, there's already a Meta Lang, abbreviated to ML.

Besides that, does it have any 'meta' features? E.g. Homoiconicity?

@okamiueru @balder1993

It's an overloaded term:

"Dependency inversion" is a language-agnostic technique for producing testable, loosely-coupled software.

"Dependency injection" just means dependencies should be passed in through the constructor, instead of being magically new()'d whereever.

"DI frameworks" are Satan's farts. Classpath-scanning nonsense that turns compile-time errors into runtime errors. Not only is your Ctr still coupled to your Svc, but both are now coupled to Spring.

An enum is a sum type because the number of inhabitants of the enum is the sum of the inhabitants of its parts.

A product type's number of inhabitants is the product of its parts' inhabitants. So a struct would fit that definition, or a pair, or a tuple.

Looking at the pic on your Cartesian product link:
if A is an enum {x,y,z} and B is an enum {1,2,3}, then a struct AxB has 9 possible inhabitants.

@onlinepersona @armchair_progamer

A type has a number of 'inhabitants'. 'Sum' indeed corresponds to adding the possible inhabitants together.

A Boolean has two inhabitants - true and false. A byte has 256 inhabitants. A BoolOrByte type has 258 inhabitants.

If you have BoolByte pair, that's a product type - 512 possible inhabitants.

It may make no fucking sense depending on your exposure to Java, where Void (literally 'empty') has an inhabitant, and Boolean has 5.

> You as the writer, you don’t know either?
Not until the compiler tells me.

> Or is the argument that nobody but the compiler and god need know? That having an awareness of the types has no value?
No, I want to know, because knowing the types has value. If the compiler has inference, it can tell me, if not, it can't.

What goes where the underscore is in the above snippet?
