Is there anything equivalent to Groovy’s remarkable SomeClass.metaClass.getProperty function in scala? This would be very helpful in making domain specific languages. For example, I could then say: val x = SomeClass(); x.arbitraryPropertyName rather than x.get("arbitraryPropertyName") or x("arbitraryPropertyName").

    From your description, this feature sounds like Scala’s Dynamic. From the Scaladoc,

    A marker trait that enables dynamic invocations. Instances x of this
    trait allow calls x.meth(args) for arbitrary method names meth and
    argument lists args. If a call is not natively supported by x, it is
    rewritten to x.applyDynamic(“meth”, args).

    That is, if your class extends Dynamic, then calls of the form x.arbitraryPropertyName get translated to x.applyDynamic("arbitraryPropertyName"), and of course you get to define the behavior of applyDynamic.
