Data::Lock makes the specified variable immutable like Readonly. Unlike Readonly
which implements immutability via tie, Data::Lock makes use of the internal flag
of perl SV so it imposes almost no penalty.

Like Readonly, Data::Lock locks not only the variable itself but also elements
therein. You can Data::Lock objects as well.

Add devel/p5-Data-Lock, a facility to mark variables as immutable. 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. 2015-03-17 17:51:19 +01:00			`Data::Lock makes the specified variable immutable like Readonly.
