Why D is annoying =P

Haha thanks a bunch for the advice. :) I was actually intending 
it to be a quick hack, not a highly-generalized thing.

So I thought, hey, I'll just use a
Tuple!(string, q{symbol}, size_t, q{iRule}, size_t, q{iSymbol})
to denote an "LR Item".



So an "item set" became RedBlackTree!(Tuple!(...)), but that 
didn't work because of the reference semantics.

So I tried int[Tuple!(...)], and hence the story.



(I actually even scrapped the idea of using a 'set' and just used 
an array.

Screw the O(n) performance.

But one of my goals was getting the code to be concise (the idea 
was to use CTFE + mixins/templates to generate some optimized 
code with switch statements for the parser), but sprinkling it 
with all the sort()s and all the code required to switch from 
hashtables to arrays just made it too ugly/indecipherable for me 
to continue working on it.)

etc.

But yeah, thanks for the advice, I'll keep it in mind. :)
