Source 2 Source compiler bug

[bundgaard]

Hello,

I'm currently going through your tutorial on "Lets build a simple interpreter".
I enjoy reading the tutorial, but I don't really understand why the change in Symbol and SymbolTable from chapter 11 to chapter 13, where much of what we already have defined, you want us to redefine?

Also I encountered, something I don't really understand with the VarSymbol scope property...

I fail to see where VarSymbol.scope.scope_level is defined,

This is from the https://github.com/rspivak/lsbasi/blob/master/part14/src2srccompiler.py#L171

        var_name = node.value
        var_symbol = self.current_scope.lookup(var_name)
        if var_symbol is None:
            raise Exception(
                "Error: Symbol(identifier) not found '%s'" % var_name
            )
        scope_level = str(var_symbol.scope.scope_level)
        return '<%s:%s>' % (var_name + scope_level, var_symbol.type.name)

and roaming around in your spi.py, I cannot find the link to .scope is it possible for you to help me out?

Thanks in advance
