it doesn't matter if objects are complex or not; the only thing that 
matters is that you must really have *objects* that can be described by 
structs, not "freeform" json. i.e. txtser cannot deserialize json into 
dom-like tree structure, only deserialize structs/arrays/aas.

but structs can contain other structs, and AA values can be structs too, 
and so on.

i.e.: if you don't need arbitrary access to arbitrary json fields, but only 
have to deserialize something with known layout, txtser probably can do the 
job for you.
