Two articles today in the “What I like about…” category. The first one is from Jorge Lugo on what he likes about Groovy. Nice write up pointing out some of the niceties that Groovy gives you over Java (I especially like the safe dereferencing - The Groovy docs call this Safe Navigation).

The second article is from Debasish Ghosh on why he likes Scala’s lexically scoped open classes. Enjoy!
