It absolutely is common. People see there is a len function that takes one argument, they call len(some_collection), see that it indeed returns the number of items in the collection like they expect and move on. They don't expect len t

These are also easier to read and write than the Python version, as you can just follow the dataflow from top to bottom (or left to right if it fits into a single line). In Python, your eyes have to jump around to find where to the next bit

rustc got bootstrapped already, so download it. If you want to run the compiler itself on a new architecture, cross-compile. If you still decide to bootstrap it again, that's something that will only need to be done once. And even in t

I have asked this question before, but why write an entirely new frontend, which is an enormous task if you want to reach a similar quality to rustc? rustc_codegen_gcc¹ adds gcc as a backend to rustc alongside llvm, miri and (wip) craneli

You don't need to write an new frontend for that, just add libgccjit as a backend for rustc.

That's how it should work. But of course last week I revisited a project I wrote in C# too, this only 3 years old, and apart from dotnet complaining about the target framework not being supported any more, I couldn't get it workin

I guess it's not strictly necessary to require a ':', but it tells people that a new variable is getting defined, instead of an existing one getting narrowed.

If you want to have a Zig compiler written in Zig, you need to bootstrap it once initially. Cross compilation makes it so you don't need to do that again when you want the compiler to work on a different architecture. Of course, there&

Despite its name, libgccjit does aot just fine, e.g. as used in rustc's gcc backend. That said, I find your definition is the most meaningful.

Since you have the concrete type, you can do stuff like storing it inline (which may not be possible if you don't know its size).

Any optimization that causes undefined behavior is bugged – please report them to your compiler's developers.

If UB happens¹, anything can happen. So if the check can only happen after UB, or leads to UB, it can be removed. That isn't the case in your example – testSomeState() can return false (and if it can't, it getting optimized out is

You don't need to switch editions, new language feature generally are available in old editions too. For example, generic associated types, which came out two weeks ago, work fine in edition 2015.

Things might be better now, but the previous false advertisement makes it really hard to tell. For example, vlang.io claims no undefined behaviour¹, but with struct Foo { bar int } println(&Foo(voidptr(some_address

++x and x++ just seem so unnecessary. Two extra operators for a very specific case, in which they either safe one character verses x+=1 or mix different mutations into the same line. Iterating a list by incrementing an index doesn't ev

In this case `query_params` works well, but it's sometimes hard to find descriptive and reasonably concise names for the intermediate value. In those cases, the ideal would be using only postfix chaining, so that you can read it by onl

Though I don't think looking at e.g. Pando and adding one to your count is particularly useful in this context.

They are two byte per item; it's the bitmaps (>4k entries) that use 1 bit per item.

Typically caching is not supposed to affect correctness, 'only' performance behavior.
