An introduction to Scala features. See associated code at http://tr.im/jA6A

2. Functional / OO hybrid

3. Statically typed

4. Compile to class files

5. Iterpretive Console

6. Flexible syntax What is it?

8. Integrates with existing libraries

9. Integrates readily with other systems (in code XML & JSON support)

10. Flexible syntax – can be like Java or can move to DSLs and higher abstractions. The name

14. Def keyword

15. Assignment of code block to function

16. scala.Console

17. Application trait See associated source files at http://tr.im/jA6A HelloWorld.scala & HelloWorldWithTrait.scala

21. Return type implies type of function

22. Naming is greatly relaxed.

25. Rich XML operations make parsing and creating XML simple.

29. Implicit def declaration

30. Multiple impicit defs, but method calls must be unambiguous at compilation Extending other classes – Monkey Patching UpperCaseCharAwareString.scala

32. Can define types based on functions signatures

35. Less than classes

36. Act as markers

37. Can have methods

38. Can have constructors

43. Case classes are parameterisable

44. Pattern Matching is akin to switch statement, but more powerful

47. Can access parent scope (closure)

48. Can be defined inline ('function literal')

51. Enumerations add values, filters remove them.

52. Lightweight notation

55. This is supported and used to construct language extensions.
