I have much of validation like this

returnif someBoolean

Answer 1

No, you can't write this operator (which would be prefix rather than infix), for two reasons:

• operators can't be defined with alphanumeric characters (see the docs for a rundown of what they can be defined with)
• you can't write a function (which is what custom operators are) that results in a return in it's calling scope ie return within the operator function would just return from the operator function, not from the function you used the operator in
