There is no such thing as a <i>straightforward longhand loop</i> in K. See also: https://nsl.com/
A natural expression for finding the indices of repeated elements (in [[ngn/k]]) might be:<syntaxhighlight lang=K>&=/'2':1 2 2 3 4 4 5
1 4</syntaxhighlight>
But of course, there's no variables here.
=={{header|Nim}}==
In Nim, a loop create a new block. Variables declared in the loop body are created and initialized at each round: they do not retain the value from one round to the next.
