I agree with Simen. Use semicolons where you separate logical parts of the  
expression like in for(each) and commas when you have an argument list or  
enumerations where all elements have the same context or meaning (hard to  
explain). So the Python syntax is [<calculation> for <counter> in <range>  
if <filter>]. I don't know if the filter is actually required, but it  
sounds like a neat idea. How about multidimensional arrays though?
