Companion module for Readonly.pm, to speed up read-only scalar variables
This is a companion module to Readonly.pm. You do not use
Readonly::XS directly. Instead, once it is installed, Readonly.pm
will detect this and will use it for creating read-only scalars. This
results in a significant speed improvement. This does not speed up
read-only arrays or hashes.
There is no official package available for openSUSE Leap 15.5
