Other than some obvious concerns, my main concern is support in the open source community. "anon" from the CoffeeScript team sent this to me after I requested input from the team to concerns I raised and wanted to get others' take on it:"Thanks for confirming that only idiots willingly program in Java and C#"
or the following from the same person:"Oh and finally, you should definitely create jShort. Even though I know
you will fail before you even start, I would love to laugh at your
attempts and it would be perfect for you since you ride the short bus.
This kind of comment reflects badly on the CoffeeScript team and hence not an option for us as a company to consider. Another example of why some open-source community projects get no traction.
