Cedalion is a programming language, different from any programming language you've encountered before.
When you think about programming languages, you probably think of text files, with lines written in some syntax that has been determined by someone you don't know, for reasons you don't always understand.
If you get the syntax wrong, you'll get a compilation error, or a runtime error. The language itself does not have the power to help you get it right from the start. There are tools and IDEs (such as some Eclipse-based editors) that help you with that, but at the end of the day, you're using a text editor to enter your code in text, hoping the language tools will understand what you meant.
