> I'm sure the reason stated by the customer support is the real one
Oh, but it's so much more beautiful than that! You're really underselling it! It's not "the reason stated by the customer support", it's:
The reason snarkily paraphrased by a Mastodon post
Which quotes a Twitter post
Which quotes a Bluesky post
Which tells a story about a conversation with an Adobe customer service rep.
Surely that tongue-in-cheek Mastodon post increases the information that we have about this incident by exactly Zero.
Right, that's the point of TFA. It doesn't list "special" operators, it lists "secret" operators -- that is, operators combined from existing sigils that do clever things.
The "Venus" operator is a good example: it's the '+' addition operator! You just add zero to a value that's coercible into a number.
The Eskimo operators are also interesting: similar to a SQL injection attack, you use a close brace and an open brace to stop and start a new code block from within a string that's sent to the interpreter. Perl didn't invent open and close braces: hence the verb "discover" rather than "implement".
The whole page is a bit of a lark, and a good example of why some of us don't enjoy Perl!
