This significantly improves parsing performance. I have also done a (small) benchmark of these changes. As can be seen the time taken to parse a context with these changes significantly decreases (in particular it is now 20x faster to parse a VC context). Before: Parse a context that has not been cached; and without caching in place x 78.17 ops/sec ±0.73% (78 runs sampled) Parse a context object that has not been cached x 2,280 ops/sec ±0.65% (91 runs sampled) in #72: Parse a context that has not been cached; and without caching in place x 123 ops/sec ±0.78% (84 runs sampled) Parse a context object that has not been cached x 5,417 ops/sec ±0.70% (87 runs sampled) After (in this PR): Parse a context that has not been cached; and without caching in place x 1,714 ops/sec ±0.78% (84 runs sampled) Parse a context object that has not been cached x 8,902 ops/sec ±0.70% (87 runs sampled)

An alternative to #71 which removes the need for any deep cloning.
