in reply to making 'use strict' default conflicts with CORE modules/scripts
No, it is not a shell variable. In fact, a shell will do the eval without even having seen the if. It's just intended to be self-documentation but work the same as "if 0". (So the code is completely unneeded, since the eval...if 0 will have already done the perlification work if necessary.)
