Re: What is missing for the seq/string types to be not nil by default?

If I understood your question correctly, you want to build a compiler with 
debugging info? 
    
    
    # this generate an additional compiler with debuging info
    # and all checks enabled that will run quite a bit slower.
    ./koch temp --debugger:native
    
    # run nim file with this debug compiler
    nim_temp c -r --debugger:native --verbosity:3 (additional args) nimfile.nim
