+  Aggregates result types from the array of items.
+
+  SYNOPSIS:
+    agg_cmp_type()
+    thd          thread handle
+    type   [out] the aggregated type
+    items        array of items to aggregate the type from
+    nitems       number of items in the array
+
+  DESCRIPTION
+    This function aggregates result types from the array of items. Found type
+    supposed to be used later for comparison of values of these items.
+    Aggregation itself is performed by the item_cmp_type() function.
+
+  NOTES
+    Aggregation rules:
+    If all items are constants the type will be aggregated from all items.
+    If there are some non-constant items then only types of non-constant
+    items will be used for aggregation.
+    If there are DATE/TIME fields/functions in the list and no string
+    fields/functions in the list then:
+      The INT_RESULT type will be used for aggregation instead of original
+      result type of any DATE/TIME field/function in the list
+      All constant items in the list will be converted to a DATE/TIME using
+      found field or result field of found function.
+
+    Implementation notes:
+      The code is equivalent to:
+      1. Check the list for presence of a STRING field/function.
+         Collect the is_const flag.
+      2. Get a Field* object to use for type coercion
+      3. Perform type conversion.
+      1 and 2 are implemented in 2 loops. The first searches for a DATE/TIME
+      field/function and checks presence of a STRING field/function.
+      The second loop works only if a DATE/TIME field/function is found.
+      It checks presence of a STRING field/function in the rest of the list.
+
+  TODO
+    1) The current implementation can produce false comparison results for
+    expressions like:
+      date_time_field BETWEEN string_field_with_dates AND string_constant
+    if the string_constant will omit some of leading zeroes.
+    In order to fully implement correct comparison of DATE/TIME the new
+    DATETIME_RESULT result type should be introduced and agg_cmp_type()
+    should return the DATE/TIME field used for the conversion. Later
+    this field can be used by comparison functions like Item_func_between to
+    convert string values to ints on the fly and thus return correct results.
+    This modification will affect functions BETWEEN, IN and CASE.
+
+    2) If in the list a DATE field/function and a DATETIME field/function
+    are present in the list then the first found field/function will be
+    used for conversion. This may lead to wrong results and probably should
+    be fixed.
