This is an new entry for the ongoing French $A++ contest. The goal is to do baroque $A++. This is not the first non alphanumeric entry but this one uses a not yet exploited obfuscation device that I let you discover.

$  {<@ >|< !>&~< ">}++

Other entries in perlmonks:

• $A++
• yet another $A++

japhy tells me he already uses this trick. He explains it in his japhy's obfuscation review.
