devel/p5-constant-defer,
constant subs with deferred value calculation
Branch: pkgsrc-2022Q4,
Version: 6nb1,
Package name: p5-constant-defer-6nb1,
Maintainer: pkgsrc-usersconstant::defer creates a subroutine which on the first call runs given
code to calculate its value, and on any subsequent calls just returns that
value, like a constant. The value code is discarded once run, allowing it
to be garbage collected.
Deferring a calculation is good if it might take a lot of work or produce
a big result but is only needed sometimes or only well into a program run.
If it's never needed then the value code never runs.
