However, the language seems to be not very stable. If a small syntax error in the program(written in this new language) happens, it can through an error message. If the syntax error is kind of critical, (e.g., a semi-colon is missed at the end of a line, or a keyword is mis-spelled) Then the whole GUI of the language crashes. Does anyone else have ever encountered similar problem? Or can anyone give me a hint on how to prevent this? Thanks a lot!
