David,

Your analysis looks very impressive.

In cr, only the parenthesized phrase is deconstructed, not ,: [: | {:
. Is that by design and due to there being no parens around the whole
of cr, (and is that also the reason each Tx result has parens around
them)?

Also, how would your code perform if the input contained non-primitives?
