Well, I do not need it on OS/2.

Setting PERL5LIB is not enough. One needs to *remove* the rest from
@INC to be sure what libraries are tested.

Not any more (in most scripts, my automated edit [intentionally] did
not cover some other syntaxes used to modify @INC).

Do you really consider
@INC = '../lib' unless $ENV{PERLTEST_KEEP_INC};
overly complicated? ;-)

As you see, I disagree. IMO, this BEGIN block plays in an important
role in *simplifying* debugging. As far as the boilerplate uses 4 or
5 "components" (such as the above @INC line), and the purpose of these
components are explained in t/README, I see no problem.
Hope this helps,
Ilya
P.S. Following this philosophy of "components",
@INC = qw(. ../lib);
should be replaced with
@INC = '../lib' unless $ENV{PERLTEST_KEEP_INC};
unshift @INC, '.';
(actually, one should use $ENV{PERLTEST_DIR) || '.' instead of '.').
