However, implementations have veered between two extremes: incredible abstractive power with a steep learning curve; and limited domain-specific uses that can be picked up in minutes. Why can't we have our cake and eat it too? #Goggles is a new #Scala macro built over the powerful & popular Monocle optics library. It uses Scala's macros and scandalously flexible syntax to create a compiler-checked mini-language to concisely construct, compose and apply optics, with a gentle, familiar interface, and extravagantly informative compiler errors. In this talk I'll introduce the motivation for lenses and why usability is a problem that so badly needs solving, and how the #GogglesLibrary, with #Monocle, helps address this in an important way. There'll be some juicy discussion of Scala macro sorcery too!
