Hello there,

Do you know why `pedersen_hash` needs to split felts in low 248 and high 4 bits?

Why does Starkware pedersen Hash Function split numbers in high and low bits

I am getting the following error: Cannot unpack the return value of 'is_le'. The return type is not a tuple.


This code was working for Cairo 0.9.1 but is not working any more:


`let (is_negative : felt) = is_le(x, -1)`


Does anyone know what this issue is about?

Cairo 0.10.0 Error: Cannot unpack return value error

I'm aware of starknet having a common--and unsafe--keccak library. Either way, I was wondering if there's a way to mimic the behavior of solidity's 
```
keccak256(abi.encode(parameters))
```
Thank you very much.

Is there a Cairo equivalent to Keccak256(abi.encode(parameters))?

Ahoy Caironauts,

  How can I define two functions with the same name but not the same arguments, e.g, 

- `func test()`
- `func test(param: Uint256)`

It is possible in Solidity and I'm trying to find the Cairo equivalent.
