Re: How important is 'use constant a => sub {};'

The fact that

    use constant a => sub {};
[download]

has problems is a big deal. Because it's correct syntax, and if something with correct syntax has "problems" (whatever they are), something is rotten.

But without telling us what the "problems" are, we can offer no guidance in solving it.

It's not a Unix thing though.

Well, the CPANPLUS makefile says it is a unix thing, kind of -- something particular to the default perl installed with this redhat distro. From the second node I linked: ### there's issues with redhat 9.0's stock perl -- they applied some ### custom patches on their 5.8.0 and it breaks use constant a => sub +{}; if( $^O eq 'linux' and -e '/etc/redhat-release' and $] == '5.008' and (grep /Red Hat, Inc/, values %Config::Config) ) { print loc(" ### IMPORTANT! ###################################################### You are using perl $] supplied by RedHat, who have applied custom patches that break various perl modules, including this one.
