perl mess I created a year ago and making this a vanilla perl installation
again, and explicitly setting the system library path so that /usr/local/*
doesn't appear anywhere.
The installed perl library now also includes CGI.pm-2.752. The www/p5-CGI
package installs in to ${PERL5_SITEARCH} so there is no conflict with the
"standard" CGI.pm.
(from commit log of perl5-current/Makefile):
* Interpreter cloning, threads, and concurrency
* Lexically scoped warning categories
* Unicode and UTF-8 support
* Support for interpolating named characters
* "our" declarations
* Support for strings represented as a vector of ordinals
* Improved Perl version numbering system
* New syntax for declaring subroutine attributes
* File and directory handles can be autovivified
* open() with more than two arguments
* 64-bit support
* Large file support
* Long doubles
* "more bits"
* Enhanced support for sort() subroutines
* C<sort $coderef @foo> allowed
* File globbing implemented internally

* Weak references
* Binary numbers supported
* Lvalue subroutines
* Some arrows may be omitted in calls through references
* Boolean assignment operators are legal lvalues
* exists() is supported on subroutine names
* exists() and delete() are supported on array elements
* Pseudo-hashes work better
* Automatic flushing of output buffers
* Better diagnostics on meaningless filehandle operations
* Where possible, buffered data discarded from duped input filehandle
* eof() has the same old magic as <>
* binmode() can be used to set :crlf and :raw modes
* C<-T> filetest recognizes UTF-8 encoded files as "text"
* system(), backticks and pipe open now reflect exec() failure

* Optional Y2K warnings
* Modules
* Pragmata

* The Perl Debugger
* Simple sort() using { $a <=> $b } and the like are optimized

* -Dusethreads means something different
* New Configure flags
* Threadedness and 64-bitness now more daring
* Long Doubles
