Thanks, Ryan. The tutorial is really good and to-the-point.

By the way, it looks like haskintex has a more general approach to 
integrating Haskell in LaTeX. It seems that in principle it could just 
use that to enable including diagrams in latex, without `diagrams-latex`.

And the same question about including a Haskell source instead of 
inlining applies. To me, having a standalone Haskell file is superior 
since I can get syntax highlighting, typechecking and even quick REPL 
debugging of diagrams that way. While with the inlined one needs to 
re-pdflatex the whole thing to get type errors (do they even show up in 
the latex output?) and reflect the changes. I guess, that could be done 
with the PGF backend for diagrams and a suitable Makefile, though.
