+ * Input iterator - explanation from Peter Dimov:
+ *
+ * Requirements say that *it is convertible to the value_type, and it is, in
+ * our case. The problem however is that op== is a template and the first
+ * argument fails deduction. std::find is specified in terms of the exact
+ * expression `*it == value`, so if it doesn't compile (and it doesn't),
+ * `find(it, it, value)` won't compile either.
+ *
+ * To address this, the no_proxy variant of the input iterator is used
+ * instead.
