The thing that strikes me forcibly is that the diagram
is much bigger than the text. Not only that, but if
I am reading it correctly, the text has three lines,
a type specification and two cases, and the diagram
covers only one of the two cases.
This isn't Ronald Guida's fault. In fact his is a very
nice looking diagram, and I could figure it out without
his explanation of the notation, *given* the textual
version to start from.
I've seen several visual programming tools, including
e-Toys in Squeak, and they tend to be really cool ways
to quickly build programs with trivial structures.
(I did not say trivial programs: you can build useful
programs that do highly non-trivial things, when the
things that are primitives _for the notation_ are
capable enough. Some data mining products have visual
wire-up-these-tools-into-a-workflow, for example.)
