Here are my thoughts: You start with a simple CLI, then you figure out you can't do much without variables, ifs and basic loops. At this point you have a language with ugly syntax and problematic semantics because it was never intended to be a language. Then you try add more features (because people a stretching the limits of what is done with the CLI) without breaking anything. This is hard and has even uglier syntax. Not mentioning names here :) CLI support is needed in NGS because in practice many scripts begin as few lines that you typed in and then copy+pasted to a file. I want to support this mode of work.
