Spring Progress Update

How should one spend one's time...

I've focused on implementation since january and have regretfully not posted any progress updates. This is what's been done since then:

• Symbol table rewrite - DONE
• Central compiler "driver" routine incl options handling - DONE
• Modules and import handling - DONE
• Generic (parameterized) types except for reentrant code generation - DONE
• Proper integer literal type handling, range checking and conversion - DONE
• Bool type and boolean expressions - DONE
• Polymorphism (virtual lookup) for static members - DONE
• Function objects retaining their closure (e.g. 'self') - DONE
• Preserve type information in references - DONE
• 'self' implicit method argument - DONE
• Virtual methods - DONE
• 'new' operator and heap allocation - DONE
• Initializers / constructors - DONE
• super() constructor invocation; super.method() invocation - DONE

My next todos are:

• Generic type instance fields support
• Interfaces
• Checked type casts (with special if statements)

But before that I need to do an important refactoring. Finding a clean way of modeling the grammar nodes, symbols, fields and types becomes rather difficult when name overloading and generic types are part of the mix. I think I've finally found the proper dimension along which to achieve separation of concern / modularization. (And as so often, in retrospect the solution looks rather trivial.)
