SIM-BE-Write methods should be able to return data

[AgustinRamiroDiaz]

In @kp2pml30 's words

"why only read methods can return values in the simulator and now write methods? in eth write methods can return something as well (and genvm supports it)"

[AgustinRamiroDiaz]

Use case:
I would like to get the address of the new contract from a factory contract, which is from a write method

    @gl.public.write
    def create_campaign(
        self,
        title: str,
        goal: str,
        knowledge_base: str,
        rules: str,
        style: str,
        token: str,
        start_datetime_iso: str,
        duration_days: int,
        missions: dict[str, dict[str, typing.Any]],
    ) -> str:
        """
        Creates a new Campaign contract and stores its address.
        Returns the address of the newly created contract.
        """
        # Deploy the new Campaign contract
        salt_nonce = len(self.contract_addresses) + 1  # salt_nonce cannot be 0
        print(f"Salt nonce: {salt_nonce}")
        campaign_address = gl.deploy_contract(
            code=campaign_code.encode("utf-8"),
            args=[
                title,
                goal,
                knowledge_base,
                rules,
                style,
                token,
                start_datetime_iso,
                duration_days,
                missions,
                self.x_id_contract,
                gl.message.sender_account,
            ],
            salt_nonce=salt_nonce,  # Use the current count as nonce
        )

        # Store the contract address
        print(f"Created campaign at address: {campaign_address}")
        self.contract_addresses.append(campaign_address.as_hex)

        return campaign_address
