This is both a comprehensive guide, and an excellent reference! I use it often when writing SML for side projects.
For those interested in parallel, functional programming, I recommend taking a look at Futhark, which leverages data parallelism to make very fast parallel programs. It is based on SML, and has similar syntax, but can automatically build programs that (among other targets) run on the GPU using CUDA or OpenCL. It is also worth checking out MPL, which extends the (already awesome) whole-program optimizing compiler MLton to add support for nested, fork-join parallelism.
