If a JSON parser does find its way into src/common, it probably wants
to have such an incremental mode available, similar to [2] offered
in the "Jackson" library for Java.

The Jackson developer has propounded a thesis[1] that such a parsing
library ought to offer "Three -- and Only Three" different styles of
API corresponding to three ways of organizing the code using the
library ([2], [3], [4], which also resemble the different APIs
supplied in Java for XML processing).
