What patch would that be? Something to do with dotted lists?

In Haskell, it seems, s-expression based syntaxes are very common as
examples in beginner tutorials so I was very happy to have something
potentially useful, but also feasible, to work on while learning.

One interesting thing, that would be harder to achieve in another language,
is that in my tests I can check that 100s of randomly generated pcbnew
expressions (pad, at, xyz, module.. etc) when written and parsed are the
same as the original (ignoring floating-point errors) so my library is
(almost) proven to be internally consistent.
