johnnywang has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I know how to change @INC:
  1. use lib
  2. Environment variable: PERL5LIB, PERLLIB
  3. directly manipulate @INC
  4. -I
But how is the default @INC constructed? how do I change that without using any of the above approach, especially 1, 3 which requires change code? Is it part of a distribution for a platform? Thanks.
