Fantom is an interesting language go and try it out! I don't think it has much traction but it is simple, easy to understand and contains some thought provoking ideas. You can get to know most of the language and most of the built in libraries with a few evenings playing with an editor and reading the online documentation. Also go and look at Ceylon and Kotlin (please, please JetBrains get some code out for Kotlin soon!), they both also contain lots of interesting ideas but are more complex than Fantom. In fact Fantom, Kotlin and Ceylon all have two features that I like, null safety and a module and dependency system baked into the language.
