@EisenbergEffect, I noticed, that code templates are duplicated for both TypeScript and ES6/ES7 versions of the generated source code.

I'm wondering, if it is worth writing both TypeScript and ES6/ES7 versions of each class. Ideally ES6/ES7 should be generated from TypeScript. I guess You have considered it? Probably TypeScript compiler can't be used to only strip the type annotations (that might be what is desired here) so probably some other tool could be used instead? TypeScript compiler removes type annotations, but additionally:

• replaces decorators with __decorate(...)
• replaces class declarations with class expressions (that is more verbose and may be harder to grasp)

What are Your thoughts?
