microlens: A tiny part of the ‘lens’ library which you can depend upon.

This is an extract from the lens library (with only 1 dependency). It's not a toy lenses library, unsuitable for “real world”, but merely a small one. It is compatible with lens, and should have same performance.

Use this library:

• if you want to define lenses or traversals in your own library, but don't want to depend on lens

• if you are new to lenses and want a small library to play with, but don't want to use something “inferior” or have to relearn things when/if you switch to lens

Don't use this library:

• if you need Isos, Prisms, indexed traversals, at, ix, or actually anything else which isn't defined here

• if you think lenses compose “in the wrong order” (in which case you're looking for fclabels)

Note that microlens has no dependencies starting from GHC 7.10 (base-4.8). Prior to that, it has to depend on transformers-0.2 or above.
