Plain Functional Programming

" summary

Argues that the useful core of functional programming is plain, specific tools: introduces implicit function types and a configured[T] alias to hide repetitive context, reports 2,600 occurrences of implicit ctx in the new Scala compiler as motivation, models exceptions with a capability type (possibly / canThrow) instead of unchecked throws, shows these are optimizable to plain methods, and uses the same implicit types to implement Kotlin/Swift-style receiver builders (table/row/cell) and to represent algebraic effects without monad transformers.
