I have written some c++ (c++11) code, that in my opinion greatly simplifies writing LibraryLink code: automatic and templatized export/import of
MTensor of any rank an type to (possibly nested) STL containers,
iostream-like argument extraction (see the github page, function
coalesce for a demo). With some polishing and documentation, I think it's something that might be handy to many.
Is stackexchange a good place to let this slip? Would that be regarded as spam?
