assignment expression

(x := 3) returns the value of x when it resolves.

so it�s just a way to do variable assignment as an expression rather than as a statement?

Yes.

It's more useful in languages with strong scoping, but it lets you eliminate some nested ifs so I think it's nice, but most of the time in python it just highlights some tortured logic that needs refactoring anyway.

It�s great for return statements.

Python code:

if cloud := butt()
    return cloud

instead of:

Python code:

cloud = butt()
if cloud:
    return cloud

anyone have a good reference handy for C# parallelism/coroutines/whatever-the-gently caress for programmers that already understand the concepts and are just trying to figure out what the specific implementations look like in c#?

if you mean parallelism in general, the magic words are task parallel library

I just stumbled upon this at work:

code:

public abstract class AbstractIterableAssert<SELF extends AbstractIterableAssert<SELF, ACTUAL, ELEMENT, ELEMENT_ASSERT>,
                                             ACTUAL extends Iterable<? extends ELEMENT>,
                                             ELEMENT,
                                             ELEMENT_ASSERT extends AbstractAssert<ELEMENT_ASSERT, ELEMENT>>
       extends AbstractAssert<SELF, ACTUAL>
       implements ObjectEnumerableAssert<SELF, ELEMENT>

(tbf, they documented it)

go does a lot of things wrong but assignment expression and the way it handles shadowing aren�t two of them

The Generics abuse by the AssertJ is nothing short of miraculous. It�s only tolerable/usable because their documentation practice is one of the best I�ve seen in Java land.

And it keeps them from having to use reflection/bytecode shenanigans more than they already do.

Look at this doofus not putting all his interfaces into a completely separate module so the sorting is hosed up no matter what you do.

ok how about this

https://pythonspeed.com/articles/faster-python/

so regular libc is faster than musl at the expense of size

however the flags you pass to build python can potentially impact performance up to 20%

i have a small project to attempt to fuzz the builds but it seems like a really stupid way to try and find other optimizations

I think ruby calls that the spaceship operator. but ruby also has flip flop operators so probably best not to follow ruby's lead

also I like the "wtf is that" feeling conveyed by "ufo"
