Wow, that's a lot of hate for what seems a fairly obvious way of extending the postfix deref mechanisms to be complete using fairly obvious syntax. Especially since these were proposed many, many years ago and I've seen several expressions of a desire for them to actually get implemented and I don't recall any significant complaints about the idea over those many years.
"Hate" is too hard I think. Apart from not all things proposed or wanted being good, it is my own fault not to be aware of that fact - but I specially: well yes, detest the @* %* $* constructs, since they blur the lines between operators, sigils and special variables.
I personally quite dislike the huge separation between tightly related parts involved in @{ ... }{@keys} when the "..." part can easily spread across multiple lines and involve a quite large number of sequential applications of all manner of postfix deref'ing.

For me, the obvious solution for convoluted @{ ... } constructs is the introduction of temporary, a.k.a. my variables in the respective scope. This serves the purpose of readability and maintainability far better than new syntactic sugar.

perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'
