>>> About to execute 'use LoadMe;' <<<
LoadMe: BEGIN is evaluated
what could go wrong?
LoadMe: UNITCHECK is evaluated
Luckily, format C: does not work on linux
LoadMe: Module initialisation
Perl is fully working and can run arbitary code, including external programs
LoadMe: import called as LoadMe->import()
Oh well, no smart comment here
>>> LoadMe was loaded <<<
LoadMe: CHECK is evaluated
Check check, is this thing on?
LoadMe: INIT is evaluated
Would I run rm -rf / ?
***** See? No code in LoadMe is executed! *****
LoadMe: END is evaluated
Good bye cruel world
