Warnings are super useful, but sometimes they become annoying, so there should be a way of muting some of them. Something like adding an annotation to a line of code that causes the warning.
Otherwise, at some point of time, when there are too many warnings, you’re risking of just ignoring them, which is bad.
Right now I have a bunch of warnings related to violation of the CEI pattern. Although I know they’re important, but sometimes you need to violate it and use some kind of reentrancy guard instead. An example for that: [flash loans in Uniswap](https://github.com/Uniswap/v2-core/blob/ee547b17853e71ed4e0101ccfd52e70d5acded58/contracts/UniswapV2Pair.sol#L172).

Hey @mpoplavkov, sorry for the long delay in the response, I was busy with other priorities. I will have @rishabhkeshan look at it and help you out here. I appreciate your patience.

Hey @mpoplavkov are you talking about our [allow attribute](https://docs.fuel.network/docs/sway/reference/attributes/) to silence some specific warnings?

Looks like what I need indeed, but where to find the full list of values I can pass to this attribute? For example, how do I mute the CEI pattern violation warnings?
