I could not find this in type_traits, or any other Boost TMP library, but I am wondering if there is any TMP technique which can determine if a user-defined type supports a particular operator overload for that type ?

Type Traits Extensions might help. It's not officially part of Boost, but it's in the review queue. -------------------------- :Author: Frédéric Bron :Review Manager: Needed :Download: https://svn.boost.org/trac/boost/browser/sandbox/type_traits :Description: The purpose of the addition is to add type traits to detect if types T and U are comparable in the sens of <, <=, >, >=, == or != operators, i.e. if t, >=, ==, !=). The following traits are added: is_equal_to_comparable is_greater_comparable is_greater_equal_comparable is_less_comparable is_less_equal_comparable is_not_equal_to_comparable The names are based on the corresponding names of the standard template library (<functional> header, section 20.3.3 of the standard). The code has the following properties: * returns true if t
