The Solidity documentation [warns](https://docs.soliditylang.org/en/v0.8.26/control-structures.html#external-function-calls:~:text=not%20be%20available.-,Warning,-Be%20careful%20that) about using the syntax `feed.info{value: 10, gas: 800}`, which only sets the `value` and amount of `gas` for the function call locally, but does not actually perform the call.

This can be misleading for beginners and could potentially be exploited in underhanded code, such as:

```auto
// Misleading function that appears to perform a refund to a smart contract
function refund(address payable recipient, uint256 amount) public payable {
    ...
    // This sets the value but does not perform the call
    recipient.call{value: refund_value};
    ...
}

```

Shouldn’t Solidity emit a warning when there are functions written in this way?
