, 15:26, 2 August 2013decision: show status bar when running exported code
* All blocks (including the ones introduced by plugins) reference a <code>Primitive</code> object, which can be called to execute the block in TA, or transformed into a Python AST.

** Type conversion and other modification of the arguments of a block is done by ''slot wrappers''. A slot wrapper is a <code>Primitive</code> that is attached to the argument of another <code>Primitive</code>. Slot wrappers are called/ transformed before the <code>Primitive</code> itself.

* The status bar may be shown when the exported code is run, as is necessary and appropriate during execution.

** How to implement this? E.g., call a <code>wait(step_time)</code> function in between two steps?
