Hehe - I wasn't clear enough there... I meant 'use-cases for a 
generalized form allowing start index to be specified'.

Although, Ralph's suggestion of allowing a counter alongside *any* 
repeat perhaps suggests the generalization *might* be worthwhile (after 
all there isn't a thing you are counting from 1 there - unlike in repeat 
for each).

So, let me rephrase - what are the use-cases people can see for allowing 
(some variant of):

    repeat ... with counter tCounter starting from tStart

Warmest Regards,

Mark.
