I just remembered my steps in TCL. There, even loops are commands which 
get some unnamed code blocks as arguments (the condition and the body).

Maybe we could do the same, based on indentation instead of {}s.

But I see some problems in handling the if: else: this way, there the 
else: command needs to know the result of the corresponding if: 
command.
