// This is useful to allow macros parameters to have commas by putting them

// inside parentheses by stripping those when expanding the macro.

// For instance, WITHOUT USING THIS, the following is an error.

// ```

// LITERT_ASSIGN_OR_RETURN(auto [a, b], SomeFunction());

// ^ ^

// The above commas make it such that the macro has 3 arguments

// ```

// Using this, the following works:

// ```

// LITERT_ASSIGN_OR_RETURN((auto [a, b]), SomeFunction());

// ^ ^

// These surround a comma, preventing it to be used as the macro

// argument separator. They are stripped internally by the macro.

// LITERT_ASSIGN_OR_RETURN(auto a, SomeFunction());

// ^^^^^^

// There is no parentheses surrounding the parameter and the macro still

// works.
