I've read that recently (maybe it was a previous comment of yours) and it's interesting that the geometry of a glyph matters. That said, a ( ... ) has a circularity that meshes well with the brain's notion of 'defined' 'finite' 'circled' 'closed' 'wrapped'. Which is often a desirable property. Any entity in lisp is simply enclosed. Any sequence is simply separated by space. Having syntactic genericity for generic trees is quite a free meal IMO.
