    (match $operator:tt::$operate:tt($inputs:expr) { $( ($input_a:ident, $input_b:ident, $input_c:ident) => $output:ident, )+ }) => { ... };
}

Creates a match statement that executes the operation.

Example

execute!(
    match Operator::add(inputs) {
        (I8, I8) => I8,
        (I16, I16) => I16,
        (I32, I32) => I32,
        (I64, I64) => I64,
        (I128, I128) => I128,
        (U8, U8) => U8,
        (U16, U16) => U16,
        (U32, U32) => U32,
        (U64, U64) => U64,
        (U128, U128) => U128,
