`in` as an operator #48

Closed tamasfe closed 2 years ago

tamasfe commented 2 years ago

We should parse in just as an operator for the sake of simplicity, then restrict its usability in the HIR where needed.

Well, it actually is an operator. It is parsed like a normal operator, except that internally it gets turned into a call to contains with the operands switched. But syntax wise, it is an operator.

It does have a different precedence though.

I assigned the lowest binding power to it for now which is just above the default user-provided ones. (yeah it's now possible to provide custom operators that are valid identifiers).

Precedence of the in operator is defined here: https://rhai.rs/book/engine/custom-op.html#operator-precedence
