Is it possible to introduce another feature

Syntax

Q: Are you going to implement the SELECT/CASE statements?

A: No. The IF statement does it very well on multiple condition. And it's also possible to put invokable objects in a dict to make a conditional executing table. Or use an alternative SELECT routine.

Q: Do you have any plan for concurrency?

A: Yes. But I won't add it to this code base, I'm going to implement it in another extension library. Very possible including coroutine and asynchronous IO operations.

Q: Is it possible to do error/exception handling elegantly?

A: Yes. It supports SEH with a TRY statement function.

Scripting API

Q: Is it possible to add more BASIC API?

A: Please read the More scripting API page for details.
