ensure			X		you don't really know the data, but want to have a default value
ensureCast			X	X	chaining
optionalGet		X			you want to handle deviating data (extens dict.get() with a type)
optionalCast				X	you want to handle non-existing keys, but don't care about deviating types
assertGet	X	X			you know the data
