Stack Overflow doesn't really support questions that do not have a specific answer, such as "What are the features you would want in a programming language that are lacked by most programming languages?". Is there a Stack Exchange site or other external site specifically made for this?
What is meta?
- Any Stack Exchange user can ask a question
- The community provides support, votes on ideas, and reports bugs
- Your voice helps shape the way Stack Exchange operates
The "What are the features you would want in a programming language that are lacked by most programming languages?" question isn't really suitable for Stack Exchange, it's a poll for opinions rather than a question on an actual practical problem. It's not a bad question, it just doesn't work with the Q&A format of Stack Exchange, as there is no sensible way of vetting answers.
We welcome some subjective questions on Programmers Stack Exchange, however your question would most likely be closed as "not constructive".
So I finally decided the only person that really answered my question was @Pekka in a comment:
And to add to his answer, one of my friend told me he asks such questions on a typical forum/message board. So I guess I'll be going for that option. Thanks to everyone who really tried to help.
