Here's another bit that seems a bit confusing... The approach does allow references to variable names with “-” embedded in them without effort, but the names must be spelled differently (and thus inconsistently) by replacing every “-” with “_”. Thus, variables like “list-ref” must be spelled as “list_ref” inside the infix.plt notation without effort. In particular the last "without effort" there seems to be something that got left behind in some edit. I also think that the bit "The approach does allow references to variable names with '-' embedded in them without effort," should be "little effort" instead, as it's not actually *without* effort, users having to translate - to _ after all.
