Marek Polacek <mpolacek at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |mpolacek at gcc dot gnu.org --- Comment #1 from Marek Polacek <mpolacek at gcc dot gnu.org> --- I'm not sure if this is valid. http://eel.is/c++draft/temp.arg.nontype#4 says A string literal ([lex.string]) is not an acceptable template-argument for a template-parameter of non-class type. but given the sv suffix, the argument should be of type basic_string_view<char>, and thus valid?
