+> If you're interested in the scholarly background on Frege's "concept horse" problem, here is [an entry point](http://philpapers.org/rec/PROWIF).
+
+> If you're reading along in Hankin, you can look at Chapter 7.
+
+> If you're reading along in the Pierce book, the chapters most relevant to this week's discussion are 22 and 23; though for context we also recommend at least Chapters 8, 9, 11, 20, and 29. We don't expect most of you to follow these recommendations now, or even to be comfortable enough yet with the material to be able to. We're providing the pointers as references that some might conceivably pursue now, and others later.

+
+> Updated notes on [[Installing and Using the Juli8 Libraries|/juli8]] on Sun 5 April. Continued to fix some bugs and improve the monad transformers. Latest version posted Monday evening, 13 April: [[v1.6|/code/Juli8-v1.6.tgz]]. This version is needed to run [[the gsv2.ml code|/code/gsv2.ml]].
+
+<!--
+The major change is to make the Monad libraries easier to use. Now you can just use `Monad.Reader(struct type env = ... end)`; you don't need to furthermore ask for the `M` submodule of that generated module. Relatedly, the `List` and `Monad.List` modules are now different; the former has lots of list-related functions and the latter only the monadic interface. Similarly for `Option` and `Monad.Option`.
