I think that a scripting system should allow the user to decompose the 
problem into smaller ones, because if not, the script could be ending in 
a 100 lines of plain code... and at the same time I think that classes 
and objects are too much for the type of problems that one specs to 
solve when scripting...
Therefore (and don't kill me for this idea), I think the script language 
should support the definition of "procedures or functions" and no more 
than that...
Doing so you can decompose a cohesive problem into smaller ones easily, 
no "bigger" abstractions are needed, and if the problem calls for bigger 
abstractions then scripting is not the solution any more...
