Those would *look* okay but wouldn't work on many Lisps (Common Lisp, Scheme).
The "|" introduces a literal atom on many Lisps.

There are currently at least 3 current implementations of sweet-expression
readers:
1. The Scheme one (tested mostly with guile)
2. Common Lisp
3. ANTLR/Java implementation (primarily for grammar analysis).
Anyone can always implement another. We want it to be as easy as possible
to implement it, while limiting the difficulties of doing so.
