+Utpl implements C-style while loops which run as long as the condition
+is fulfilled.
+
+Like with for-loops, an alternative syntax form suitable for template
+blocks is supported.

+-- Expect stdout --
+A simple counting while-loop:
+Iteration 0
+Iteration 1
+Iteration 2
+Iteration 3
+Iteration 4
+Iteration 5
+Iteration 6
+Iteration 7
+Iteration 8
+Iteration 9
+
+
+If the loop body consists of only one statement, the curly braces
+may be omitted:
+Iteration 0
+Iteration 1
+Iteration 2
+Iteration 3
+Iteration 4
+Iteration 5
+Iteration 6
