Expand Up @@ -494,12 +494,13 @@ The array C<@INC> contains the list of places that the C<do EXPR>,
C<require>, or C<use> constructs look for their library files. It
initially consists of the arguments to any B<-I> command-line
switches, followed by the default Perl library, probably
F</usr/local/lib/perl>, followed by ".", to represent the current
directory. ("." will not be appended if taint checks are enabled,
either by C<-T> or by C<-t>, or if configured not to do so by the
C<-Ddefault_inc_excludes_dot> compile time option.) If you need to
modify this at runtime, you should use the C<use lib> pragma to get
the machine-dependent library properly loaded also:
F</usr/local/lib/perl>.
Since Perl 5.26 '.' which represents the current directory
is not appended anymore to C<@INC>. This is not recommended to change
this behavior and you can read more about it from
L<C<PERL_USE_UNSAFE_INC>|perlrun/PERL_USE_UNSAFE_INC>
If you need to modify C<@INC> at runtime, you should use
the C<use lib> pragma to get the machine-dependent library properly loaded also:

use lib '/mypath/libdir/';
use SomeMod;
