+// SFINAE-compatible wrapper for `std::to_address()`.
+//
+// The standard does not require `std::to_address()` to be SFINAE-compatible
+// when code attempts instantiation with non-pointer-like types, and libstdc++'s
+// implementation hard errors. For the sake of templated code that wants simple,
+// unified handling, Chromium instead uses this wrapper, which provides that
+// guarantee. This allows code to use "`to_address()` would be valid here" as a
+// constraint to detect pointer-like types.
