I stumbled across mentions of "method" as a synonym for "class member
function" or "class member function template"

• [mem.poly.allocator.mem]/8
  [ Note: This method and the construct methods that follow are overloads
  for piecewise construction of pairs(20.4.2). —endnote]

• [string.view.iterators]/2
  For a basic_string_view str, any operation that invalidates a pointer in
  the range [str.data(),
  str.data() + str.size()) invalidates pointers, iterators, and references
  returned from str’s methods.

I suppose those should be replaced by "class member function" or "class
member function" as appropriate?

I believe that's editorial.

Cheers, Axel.
