It is comparable to p5-Readonly (but much faster; see https://metacpan.org/pod/Data::Lock#BENCHMARK), or to the constant pragma (except it retains sigils). It includes Data::Lock and its dlock() function which handles scalars, and Attribute::Constant which exports a ': Constant' attribute, which is faster but has caveats. END
