                    plus suffix return type
           Product: gcc
           Version: 4.8.1

In gcc 4.8.1,

The following doesn't seems to work:

using to_lower_fn_ptr = [](input_base_type, const std::locale&) ->
input_base_type;



When compile it gives the following error:

error: expected type-specifier before '[' token
     using to_lower_fn_ptr = [](input_base_type, const std::locale&) ->
input_base_type;
