The value code is discarded once run, allowing it to be garbage\ncollected.\n\nDeferring a calculation is good if it might take a lot of work or produce a big\nresult but is only needed sometimes or only well into a program run. If it's\nnever needed then the value code never runs.\n\nA deferred constant is generally not inlined or folded (see \"Constant Folding\"\nin perlop) since it's not a single scalar value. In the current implementation a\ndeferred constant becomes a plain constant after the first use, so may inline\netc in code compiled after that (see \"IMPLEMENTATION\" below).","flavors":[],"html":"https://daemonports.org/devel/p5-constant-defer/","kind":"port","lastUpdate":null,"license":["GPLv3"],"maintainer":"sunpoet@FreeBSD.org","name":"p5-constant-defer","newest":true,"newestVersion":"6","noVulnData":false,"origin":"devel/p5-constant-defer","otherSystems":[{"maintainer":"pkgsrc-users@NetBSD.org","newest":true,"origin":"devel/p5-constant-defer","path":"/netbsd/devel/p5-constant-defer/","system":"NetBSD","updated":"2026-07-16","version":"6nb5"},{"maintainer":"sunpoet@FreeBSD.org","newest":true,"origin":"devel/p5-constant-defer","path":"/dragonfly/devel/p5-constant-defer/","system":"DragonFly","version":"6"},{"maintainer":"sunpoet@FreeBSD.org","newest":true,"noVulnData":true,"origin":"devel/p5-constant-defer","path":"","system":"HardenedBSD","version":"6"},{"maintainer":"sunpoet@FreeBSD.org","newest":true,"noVulnData":true,"origin":"devel/p5-constant-defer","path":"","system":"GhostBSD","version":"6"}],"packages":[{"repo":"FreeBSD:14:latest","versions":["6","6","6","6","6"]},{"repo":"FreeBSD:14:quarterly","versions":["6","6","n/a","6","6"]},{"repo":"FreeBSD:15:latest","versions":["6","6","n/a","6","6"]},{"repo":"FreeBSD:15:quarterly","versions":["6","6","n/a","n/a","n/a"]},{"repo":"FreeBSD:16:latest","versions":["6","6","n/a","n/a","n/a"]},{"repo":"FreeBSD:16:quarterly","versions":["n/a","n/a","n/a","n/a","n/a"]}],"pkgName":"p5-constant-defer-6","related":null,"repository":"FreeBSD ports","requiredBy":["textproc/p5-HTML-FormatExternal","www/p5-RT-Extension-RepeatTicket2","www/p5-RTx-Calendar","www/rt50","www/rt60"],"requiredByCount":5,"runDepends":["lang/perl5.42"],"status":null,"system":"freebsd","systemLabel":"FreeBSD","version":"6","versions":null,"vulnerabilities":null,"www":"https://metacpan.org/release/constant-defer"}
