OK. Emphasis metaprogramming can
present challenges.High Huge and active
Metaprogramming is sometimes abused. RoR is too magical and many imitated its philosophy
Stable, but much catchup remaining for gems to support 1.9
Tough. Medium learning curve, hard to find
seasoned devs
Concise, expressive but NOT simple.
Highly variable! Small and activeToo many ways to accomplish
things. Scala “implicits” encourage magic
Language spec changing, breakages still occurring in dot
releases
Very difficult. Steep learning
curve
Highly readable High Big and active Explicit better than implicitMost mature here.
But the 2.x/3.x break is bad.
OK. Shallow learning curve.
