Really outstanding talk, the demo of C++ interop was inspirational.

How to get n-th symbol of utf-8 string

Note the difference: `runeAtPos` returns a `Rune` (the Unicode equivalent of `char`), `runeStrAtPos` returns a `string` (like in Python).

How to overload procedure correctly?

It's not _quite_ the same as in Python, because the concrete type must be known at compile time. But here it works.

Is there more simple way to solve this task?

type Point2D = tuple[x, y: float] func sumPoints(p1, p2: Point2D): Point2D = (p1.x + p2.x, p1.y + p2.y) echo sumPoints((x:1.0, y:2.0), (x:3.0, y:4.0)) Don't be repeating the type in the args, nor failing to qualify the x, y parameters in the call.

`proc sum(a: int, b: int): int = a + b proc sum(a: int | float, b: int | float): float = float(a) + float(b) echo sum(1, 2) echo sum(1.0, 2) echo sum(1, 2.0) echo sum(1.0, 2.0) ` Run

Cool! `int | float` is like in Python 3.10! Many thanks!

How to overload procedure correctly?

It is basically what you want to do, but already done. You can sum int and float mixed and it works, after importing it `echo 1.0 + 2` works. You can see the source code

Question about procedure parameters

It does not matter whether you use let of var to declared variable inside of a procedure, it will all work the same. Procedure with `let nprinted = if nprinted == -1 : s.len else: min(nprinted, s.len)` is identical to `var nprinted = if nprinted == -1 : s.len else: min(nprinted, s.len)`, at leas

How to overload procedure correctly?

I need to create a procedure to sum `a` and `b` (for study purposes). Variable `a` can be `int` or `float`, variable `b` can be `int` or `float` too. My code works, but I wonder if there is more simple way to do overloading: proc sum(a: int, b: int): int = a + b proc sum(a: int,

According to your answer it seems to be available, but it's difficult for me to understand this material... Could you post how this will be look for my case?

How to overload procedure correctly?

You can use generics like this: `proc sum[T, Y](a: T, b: Y): float = float(a) + float(b)`

Question about procedure parameters

So, when I use `var` unstead of `let`, I will change procedure parameter, willn't I?

Question about procedure parameters

According this in [Nim tutorial](https://nim-lang.org/docs/tut1.html#procedures-parameters): > Parameters are immutable in the procedure body. By default, their value > cannot be changed because this allows the compiler to implement parameter > passing in the most efficient way. If a mutable va

Question about procedure parameters

Let creates a new variable that happens to share the name with the argument. But they are different memory locations. This is what happens: proc printSeq(s: seq, nprinted0: int = -1) = let nprinted1 = if nprinted0 == -1 : s.len else: min(nprinted0, s.len) for i in 0
