Compiler flags enable customization of the compiler’s behavior within the scope of a specific function. These flags are particularly useful for managing edge cases by temporarily relaxing certain restrictions. Below is a list of available compiler flags and their functions:

• allow_nested_if_else - Disables warnings that recommend using specialized if-chain syntax.
• allow_generic_return - Suppresses warnings that prompt the developer to specify a concrete return type when using arguments with defined types.
• allow_absurd_cast - Turns off warnings about the potential for nonsensical results when using force-type casting, which may result in an absurd cast.

#[allow_nested_if_else]
fun foo() {
    // ...
}
