still another $A++

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:

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

Hint: I abused in japhy's obfuscation review. Granted, not with the wacky non-alphanumerics, but the trick was the same. _____________________________________________________ Jeff`[japhy]`Pinyan: Perl, regex, and perl hacker. `s++=END;++y(;-P)}y js++=;shajsj<++y(p-q)}?print:??;`	[reply]

I did not know that it was already exploited but in your node you missed the opportunity to throw in spaces to make identification of this obfuscation device less obvious :) About this node, you said "Clutter can help obfuscate". I would add: spacing can help to obfuscate when used to mask syntactical structures or, worse, hints at non valid interpretations. -- stefp	[reply]

Here is another $A++ on Perlmonks you forgot: $A++ under constraints This one is aimed at using only characters between `@` and `DEL`.	[reply]

Works with linux, bash and perl 5.6.1: `echo 2 >"1 "`;open 1,1; $A += chomp ($a =<1>); -- stefp	[reply] [d/l]
