As mentioned, to get your macro to work, you have to change how the
reader behaves on "|".
You might be interested in the (implementation of) no-vert-bar reader lang:

You're right that `|` isn't a valid terminal with the normal reader, but,
as it happens, the zero-length identifier can be written as `||`. (I don't
think the concept of a zero-length identifier is common in other languages:
it corresponds to the empty string.)

Hi guys,
I’ve been trying to figure out how to use “|” in a macro. I’ve got syntax like
this in mind:
(foo A | B)
Not sure if I can do this because the reader expects a pair. If “|” isn’t a
convenient literal to work with is there an alternative others have used that
represents more
