semantics, such as strict, given-when syntax, Unicode strings, signatures, ... See
L<feature> documentation and source code for more information.

=item C<use utf8>

This is NOT related to handling UTF-8 strings or input/output (see
C<use feature 'unicode_strings'> imported with C<use v5.20> for
something more related to that).

C<use utf8> is imported in order to allow UTF-8 characters inside the source
code: while using UTF-8 in the source is not standard procedure, it
happens to me every now and then. Also, enabling this feature does
no harm if you're using a recent version of perl, so why not enable it?

=item C<use warnings FATAL =E<gt> 'all'>

Warnings are useful, who wouldn't want them?

However, if they are not treated as fatal errors, they are often
ignored, making them pointless. So, be fatal!

=item C<no warnings 'uninitialized'>

Well, I<most> warnings are useful. The ones regarding uninitialized (undef)
variables are a bit of a pain. Writing a code such as this:

    my $str;
    
    if ( $str eq 'maya' ) {
        say 'Maya!';
    }

would emit a warning, thus forcing you to write:

    my $str;
    
    if ( defined $str && $str eq 'maya' ) {
        say 'Maya!';
    }

which is boring enough to justify suppressing these warnings.

=item C<use Carp qw/carp croak confess cluck/>

These functions are very useful to show error details better
than that of C<die()> and C<warn()>.

=item C<use experimental 'try'>

Try - catch - finally... finally!

=item C<use experimental 'defer'>

Defer blocks seem to be very useful.

=head1 WARNING

The 5.36 version of this module is not compatible with the previous one,
bcause it replaces L<Try::Tiny> with Perl's own new Try/Catch syntax,
and discards the obsoleted C<postderef> syntax.
