thanks for pointing that out, completely forgot about lisps!

i get that, i just think it'd be nice if they could be used for run-time stuff too – why create a gap between the compile- and run-time parts of the language? it seems like desugaring it into a loop should be pretty straightforward¹; i

i've never seen a programming language implement math-y notation in the vein of xs[0] + ... + xs[n] so that's kind of cool... though C++ seems like an odd place to find it. i wonder how expressive it is, i.e. what the limit

by uryga 6y ago
it's a rough rule of thumb at best though – higher-order-functions or other things that take a callback blur the line a lot (IoC, what a sibling comment said). or say a library has an event-loop, or maybe does networking and you only p

i always read frontend/backend as an analogy to how e.g. a store has a front (for customers) and back (not for customers), or like how a stage has a back-stage. so the metaphor, and "semantic connection" would be that "b

i was going to mention this, but the comment was already long :) of course, this doesn't stop you from implementing it as stackPop _ = Nothing or just doing the wrong thing. but it does prevent you from returning `([1,2,3], No

just realized my usage example is misleading. as sibling comments correctly explain, \35 means chr(0x35) == '\x35' == '5' so the actual usage would be <div class="5">

by uryga 6y ago
i guess it's "making illegal states unrepresentable" – with `(Stack a, Maybe a)` you allow an implementation that does stackPop [1,2,3,4] == ([1,2,3], Nothing) which doesn't make sense - `Nothing` is only supposed

that's `init` in Haskell, and in this case i'd agree with the OP - i'm used to `pop` letting you actually access the last element, so i'd prefer a different name. also, doing it that way will require traversing the struc

by uryga 6y ago
so we agree about single-return-pop – it just wouldn't be very useful. what i tried to say is that it's a bit of a strawman – single-return-pop is pretty obviously useless, so no one would design a pure API like that. so there&#x2

> So as long as 'pop' is returning the element from the list/map/set/whatever, and nothing else, it is the wrong verb for immutable structures. right, but would anyone really write a functional `pop` like that?

TIL! as with most languages, css indentifiers can't start with numbers, but you can get around that using backslash-escapes. you'd use these classes like this: <div class="35"> this stackoverflow answer has

i guess i was being a bit pedantic... as you say, if you look at Clojure's whole programming environment (tooling, stdlib) and not just the language itself, putting it like GP did makes sense.
