This release implements 6.c and 6.d versions of the Raku specification.
6.c version of the language is available if you use the use v6.c
version pragma, otherwise 6.d is the default.

Upcoming releases in 2025 will include new functionality that is not
part of 6.c or 6.d specifications, available with a lexically scoped
pragma. Our goal is to ensure that anything that is tested as part of
6.c and 6.d specifications will continue to work unchanged. There may
be incremental spec releases this year as well.
