Detailed Description

template<class T, class charT = char, class traits = std::char_traits<charT>>
class infix_ostream_iterator< T, charT, traits >

GCC9 currently hits a "no type named 'value_type'" error during build if this is removed and iterator traits are listed within the class corresponding to the C++17 standard.

This preserves use of std::iterator for GCC9 and earlier.
