  // Basically, the way to make sure a static_assert only fires if a template
  // is actually instantiated (rather than every time the file is parsed) is to
  // use template parameters in the expression, e.g. FuncType here. However,
  // since `sizeof(FuncType) != sizeof(FuncType)` is always false, this has the
  // same effect.

      "- (your function type) is the unsupported signature.");
