programming theorization and design based on information content ?

instead of copying and mutating data, layer and intercept ? lazy and virtual

adding two strings yields an entity knowing about the two strings and how to be a string based on the idea of concatenation, no need to recreate a new string of both content

str s \
         ,`- str u
str t /

it's all good in systems were information chunks aren't mutated, erased by local agents
