Does anyone know if C ++ 11 function templates can partially specialize?
No, they cannot. The draft C ++ 0x standard has a section (14.5.5) on partial specializations of a template template, but no mention is made of partial specializations of function templates.
No they were proposed as the main language issue # 229 (from n1295 ), but ultimately rejected (and quite rightly, since overloading does the job).
