we weren't actually using these sources anymore, okay?

-// ABSL_ARRAYSIZE()
-//
-// Returns the number of elements in an array as a compile-time constant, which
-// can be used in defining new arrays. If you use this macro on a pointer by

-// ABSL_BAD_CALL_IF()
-//
-// Used on a function overload to trap bad calls: any call that matches the
-// overload will cause a compile-time error. This macro uses a clang-specific
-// "enable_if" attribute, as described at
-// https://clang.llvm.org/docs/AttributeReference.html#enable-if
-//
-// Overloads which use this macro should be bracketed by
-// `#ifdef ABSL_BAD_CALL_IF`.
-//
-// Example:
-//
-//   int isdigit(int c);
-//   #ifdef ABSL_BAD_CALL_IF
-//   int isdigit(int c)
-//     ABSL_BAD_CALL_IF(c <= -1 || c > 255,
-//                       "'c' must have the value of an unsigned char or EOF");

-// ABSL_ASSERT()
-//
-// In C++11, `assert` can't be used portably within constexpr functions.
-// ABSL_ASSERT functions as a runtime assert but works in C++11 constexpr
-// functions.  Example:
-//
-// constexpr double Divide(double a, double b) {
-//   return ABSL_ASSERT(b != 0), a / b;
-// }
-//
-// This macro is inspired by
-// https://akrzemi1.wordpress.com/2017/05/18/asserts-in-constexpr-functions/
