> Profiliing deserialization of test "Address" object shows that we spend considerable
amount of time (10-20%) inside field ID calculation. 
> We already optimized this for writes using serialization "paths" concept where field
hashing is replaced with strings reference equality checks. The same thing should be done
for reads.
