I forgot to remind you: Don't hesitate to ask LDC-specific 
questions in
the LDC gitter [1]. Apart from the fact that it's very welcome,
you also have a better chance that seasoned developers will see 
it and/or
answer like kinke and Johan (although they will probably see it 
here too).

I personally don't have any experience with those files. Bear in 
mind that
in my experience, questions about constrained situations (like, 
oh in the visit of
ClassDeclaration I don't understand the x) are easier to answer 
than broad ones.

Now that you mentioned it though, you reminded me that LDC does 
not have
a header description for a file (like on the top of every file, 
describing
what the file does roughly). I find this useful. I also find 
useful
a source guide like DMD's [2]. I'm trying to construct one on my 
own bit by bit.
If along the course of your project you're interested to 
contribute to the
documentation, let me know.

For now, you can safely ignore the last paragraph, I just left it 
there
for future reference. One thing to have in mind though is that 
you probably
will need to get somewhat comfortable with the DMD source code, 
so this
DMD guide might help.
