If you are going for short code then the following scala example:

val arrayTwo = arrayOne.map { item:Int => item + 1 }

Can be written like this:

val arrayTwo = arrayOne.map(_+1)

"the availability of ruby gems is highly superior to the amount of SBT dependencies"

SBT is just a questionable version of Maven and I would bet money the amount of Java/Scala libs available in Maven repositories far exceeds the number of Ruby gems available.

Stupid article, stupid comparison.

good god i hope not. we don't need that faux rockstar culture in my pretty language.
