1. The syntax parsing wasn't complete. In retrospect parsing "class foo {}" perhaps should not have been my sole benchmark for completeness... it took another 4 hours or so to get "class foo { int y; }" parsing. Debugging parsers is hard.
(For those interested, the problem involved my uneducatedness biting me in the ass again. I realized that something of the form token: (element|token delimiter element) would require special attention, though I failed to generalize the recursion properly...)
2. I overestimated the gains I would get from compiling something almost C# into C#. Sure, a nice optimizing C# compiler is at hand, and the BNF, and libraries and interoperability... but all the lexing/parsing errors are unavailable to me and will need to be replicated. And if I'm going to do anything remotely interesting I'm going to have to do a lot of the type checking symbol table stuff.
It sure does make me appreciate a little more the complexity of such an endeavor and might make me a little more forgiving of the crappy error messages compilers are often giving me.
More Setbacks to come and maybe some actual progress too one day now that I can keep an eye out for coding while a little too pleased with my progress...
