How to loop through stacks with same name?

[Alex Tweedly]

Jacque,

those two code snippets do slightly different things - and I don't think 
either of them is doing exactly what's intended; I think the intent is 
to delete stack(s) called (exactly) "test".

The first one will (wrongly) catch a stack called "testabc" or "abctest" 
- and then will fail on deleting 'test'.

The second one also catches "testabc" - but in this case deletes it 
unintentionally.

Alternatively, we could go straight to the point

again, the timings are overlapping - the variation between different 
runs far outweighs the difference between the methods. I think that 
could be different if there many other mainstacks in play, but I don't 
see that it would be significant in any realistic case.

So pick the one that seems  most easily read and understood :-)
