I want to standardize existing practice, not propose something novel.

Existing practice

  * works with something that looks like an array
  * does not execute code at runtime during the registration
  * does not require mutable memory, which is a security issue (see the
EncodePointer function :
https://learn.microsoft.com/en-us/previous-versions/bb432254(v=vs.85) )

The proposed linked list cannot be compared with such approach.

I was also thinking that exposing span or initializer_list are viable
alternatives.
They have the advantage that there is no need for a second symbol for
tracking the size.
