uint is hardly supported, the type is known, but no operations can be done
yet. I advise to use 'int' in your scripting interfaces. The only solution to
this is writing a constructor for uint which takes an int as argument, such
that you can write

 var uint a = uint( -3 );

But we could also define auto-conversion rules in the scripting syntax, which
is a feature requiring more implementation work than adding the constructor.

Talking about features, another thing I miss often is the ability to define
variables in the taskbrowser prompt:

 var int a = 3
 now use 'a' in taskbrowser prompt

The variable 'a' would then be added to the interface of the current
component. Technically it is even possible to drop the 'var' prefix in the
taskbrowser.
