How has support for ithreads limitations changed across recent Perl versions?

Support for ithreads (interpreter threads) in Perl has evolved significantly over recent versions. Initially, ithreads were considered experimental and had several limitations, especially around complex data sharing and certain core modules. However, as Perl has matured, many of these restrictions have been alleviated or resolved, enabling more robust multi-threading capabilities.

In recent versions, particularly from Perl 5.8 onward, enhancements include improved memory management, better handling of shared variables, and the addition of new modules specifically designed for threading. Developers can now take advantage of ithreads for user interface applications, parallel processing tasks, and other multi-threaded solutions.

For example, here's a simple demonstration of creating and using ithreads in Perl:

use threads; my $thr = threads->create(sub { print "This is a thread\n"; }); $thr->join();
