While it is expected that grouping decimal literals by 3 will be a=0A=
frequent use case, the RFC does not enforce an arbitrary group size.=0A=
Not only would doing so add complexity, but it would also prevent=0A=
some of the use cases mentioned in the RFC. For example, if you're=0A=
working with financial quantities stored as cents, it can be useful=0A=
to group the dollar amount by 3 and the cents by 2:=0A=
=0A=
```php=0A=
$amount =3D 100_500_00; // represents $100,500.00=0A=
```=0A=
=0A=
The RFC also contains examples of grouping hex and binary literals by=0A=
2, 4, or 8 digits.=0A=
=0A=
Not placing restrictions on the size of digit groups enables=0A=
programmers to choose the grouping that best reflects their intent.=0A=
It's also consistent with the other languages that support this=0A=
feature.=0A=
=0A=

=0A=
That's fine. Not everyone has a use case for this feature, but it can=0A=
be very helpful for those that do.=0A=
=0A=
