PClasses are declared as python classes inheriting from PClass. It is defined the same way that PRecords are and behaves like a PRecord in all aspects except that it is not a PMap and hence not a collection but rather a plain Python object. More documentation and examples of PClass usage is available at https://github.com/tobgu/pyrsistent c  sRtt||}|dd}|dd}g}g}|jD]\}}||vr|dusZ||vrtt||rz|j|||d} q|||} n||} t|||| ||||=q:|j t urt |j r| n|j } t|||| ||q:|j r:| d|j|q:|s |rtt|t|d|r>> from pyrsistent import PClass, field >>> class AClass(PClass): ... x = field() ... >>> a = AClass(x=1) >>> a2 = a.set(x=2) >>> a3 = a.set('x', 3) >>> a AClass(x=1) >>> a2 AClass(x=2) >>> a3 AClass(x=3) rrr3)setrgetattr_MISSING_VALUEr%)selfargsr>r?rr.rrrr@Rs   z PClass.setNFcs:t|rS|r&fdd|jD|f||dS)a: Factory method.
