So normally I go with a super-conservative error handler that logs errors, and exit the process on even the tinyest/smallest error.
Regardless or project/cms/framework I always to this to prevent myself from installing spaghetti plugins or writing unstable code.
Also because I don't want any code to just soldier on if a variable wasn't defined properly, or likewise.

But today I had to write this little fucker into my error handler, to support the error surpressing operator '@'

Appearently prestashop was developed by a group of senseless moronic fuckwits,
and hteir piece of horseshit software doesn't even work if it isn't allowed to surpress errors.

What was the fucking imbeciles thinking when requiring such lunatic behaviour...
