Very cool Bob! I'm a big fan of your writing and Jasic was a nice and small project that really helped me understand compilers better. I look forward to my lunch hour when I can go over this chapter.

I'm actually going through a similar process at the moment. I would like to write a few articles about implementation considerations in compilers that text books often omit. For example, in the scanner phase, should identifier tokens contain a copy of the identifier name, should they have a length + pointer into the original stream, should they contain an index into a symbol table, etc.
