Thanks for replying. It seems GO is not for me at least now. What I want is an optional strong typed script language with highest performance. Lisp serves me well here. I have only three real things to care about a language: 1. Performance and thus optional strong typed is required. Go can have optional strong typed system, so performance may be improved in future, but its GC seems a big warning for me. I want to have option to allocate/free memory myself. the GC is also an enforcement of some design principle, which is also a big minus regarding the next point. 2. Great flexibility, basically the language should not make any decisions for developers. I dislike C++ for its OOP approach to make way too many decisions for developer. I want no limitation from a language. I can self restrain to avoid all troubles from freedom, I can design OOP/GC myself if it is neccessary, but please not make decision for me. (C++ did not enforce OOP, but most of the extra part beyond C usually distorts a good design otherwise) Lisp and C are almost perfect here. Does GO allow any weird design people may think of? any enforcement of some supposed-to-be good principle? 3. A script, which can relieve me on all details. Occasionally, I may not care performance, and I want life easy. Python is prety good here. Lisp is good but lack of compiling on ARM machines is a big disadvantage.
