% perl -E '$notset'
% perl -e 'use 5.012; $notset'
Global symbol "$notset" requires explicit package name at -e line 1.
Execution of -e aborted due to compilation errors.
C<use 5.012> enables feature.pm *and* strictures (without loading strict.pm).
-E (on 5.012) is the same as
% perl -e 'use feature ":5.12"'
But how to document this generically?
% perl -e 'use feature ":$^V"'
Feature bundle "v5.12.1" is not supported by Perl 5.12.1 at -e line 1
BEGIN failed--compilation aborted at -e line 1.
% perl -e 'use feature ":$]"'
Feature bundle "5.012001" is not supported by Perl 5.12.1 at -e line 1
BEGIN failed--compilation aborted at -e line 1.
