Improve Data Statement

Registered by Eike on 2010-07-10

The data statement needs an own a mini language, so that common ways of configuring objects can be done. This mini language should be flexible and extensible, so it can be used in the compile statement too.

Tasks are specifying: type, role, unit, default value, value, ...
An example a good mini language are Python's function parameters.

Whiteboard

- Syntax for the data/compile statement should have arbitrary keywords.

- Maybe a syntax for anonymous structured component types, complicated structures can be specified in a compact
  way. Especially interesting in conjunction with tree literals.
      data a:
          data b,c: Float param
          data d: String const
