Comment (by costdev):

 Here's a link to confirm that this change will still work:
 https://3v4l.org/L7aNL

 This change is worth making for the following reasons:
 - **Readability** - When scanning code, single- or double-quoted array
 keys will read as associative arrays at first glance. This change makes it
 immediately clear that this is a numeric array.

 - **Performance** - See the "Time with string|int" results in the output
 of the link above.

 - **Consistency** - Numeric keys should be written as integers.

 - **Cross-version PHP support** - As shown in the link above, this change
 will work across PHP versions.

 IMO, this patch is ready for `commit` in time for Beta 1 today.

 Any other occurrences of numeric `string` keys in core should be removed
 in a follow-up ticket.
