Macro for_all_op3

macro_rules! for_all_op3 {
    () => { ... };
}

Defines a macro that expands to include a set of three-element operations used within the expression handling of string synthesis tasks.

This macro uses the _do! macro utility to list the operations Replace, Ite, SubStr, and IndexOf, which are likely shorthand references to more complex operations involving three arguments or parameters. The purpose is to simplify the repetitive task of writing out these operations each time they need to be applied, enabling more concise and modular code within areas of the project that handle ternary operations.
