+`break` or `continue` keywords were used in a condition of a `while` loop
+without a label.
+
+Erroneous code code:
+
+```compile_fail,E0590
+while break {}
+```
+
+`break` or `continue` must include a label when used in the condition of a
+`while` loop.
+
+To fix this, add a label specifying which loop is being broken out of:
+
+```
+'foo: while break 'foo {}
+```
