Parametric lenses [PDF]

open access: yesProceedings of the 26nd 2014 International Symposium on Implementation and Application of Functional Languages, 2014
Most complex applications inevitably need to maintain dependencies between subsystems based on some shared data. The dependent parts must be informed that the shared information is changed. As every actual notification has some communication cost, and every triggered task has associated computation cost, it is crucial for the overall performance of the
