Operator Functions

In Reason, we can use functions to create our own customized operators. The purpose of the operator will be defined within the function.

All the predefined in-fix operators can be used to create new in-fix operators. The same goes for prefix operators.

In fact, operators are functions. This implies that we can create our own operators just like we can create our own functions.

The Template

Below, we can see that the template for creating operators is almost identical to that of functions:
