Having been burnt before, I had the luxury of being able to wait a few days (unlike cavac).

With no new PM questions posted today, I decided to build perl v5.38.2 from source, using the same steps as last time (but installed into $HOME/my/p5382 this time, i.e. $ type perl - perl is hashed $HOME/my/p5382/bin/perl) and it seems to be working nicely so far, at least kcott's and Tux's superb Unicode utilities are both working flawlessly. :)

Of course, having just completed that chore, I'm half expecting an urgent new perl v5.38.3 to be rushed out tomorrow (hope saying that doesn't jinx cavac's pyramid building :).

Extra Modules Installed Later (Update)

Got errors using kcott's perlu alias (described at Re^2: Another Unicode/emoji question) ... to remedy, installed IPC::System::Simple:

$ alias perlu='perl -Mstrict -Mwarnings -Mautodie=:all -Mutf8 -C -E'
$ type perlu
perlu is aliased to `perl -Mstrict -Mwarnings -Mautodie=:all -Mutf8 -C
+ -E'
$ perlu 'say chr 0x1f436; say chr 128054;'
IPC::System::Simple required for Fatalised/autodying system() at -e li
+ne 0.
        main::BEGIN() called at -e line 0
        eval {...} called at -e line 0
BEGIN failed--compilation aborted.

As noted at SO question, it seems strange that a core functionality requires a non-core module, and quietly too (doesn't complain at installation). See also: perl-autodie missing dependency for IPC::System::Simple (RedHat bugzilla).

This fixed my perlu issue:

$ type perl
perl is hashed ($HOME/my/p5382/bin/perl)
$ cd $HOME/my/p5382
$ cpanm --from https://www.cpan.org/ --verify IPC::System::Simple 2>&1
+ | tee IPC-System-Simple.tmp

Later, installed Data::Dump and List::MoreUtils and Module::Starter:

$ cd $HOME/my/p5382
$ cpanm --from https://www.cpan.org --verify Data::Dump 2>&1 | tee Dat
+a-Dump.tmp

+e List-MoreUtils.tmp
$ cpanm --from https://www.cpan.org --verify Module::Starter 2>&1 | te
+e Module-Starter.tmp

TODO: Install more CPAN modules (e.g. List::AllUtils and stuff by PEVANS e.g. List::UtilsBy, List::Keywords, ...). Further analysis of perlrun and utf8.
