My mistake it actually avoids initialising the loop variable rather than 
not declaring it:

for i in myarray do
   myarray[i] := 0;

as opposed to

for i := low(myarray) to high (myarray) do
    myarray[i] := 0;

I think the for..in is much clearer and more compact (it works for sets, 
arrays and other enumerated types)
