Back in the days when I first learned that local also works for hash elements, I was very surprised. (How random! Why? ¹)

But now that I realize that every local is actually operating on hash elements, this finally makes a lot of sense. :)

(stash= symbol table hash, and a typeglob is very similar to a hash, just with a fixed number of slots)

Updates

¹) And most confusingly, why does it suddenly work for lexical hashes too???

DB<2> my %h=(a=>1); { local $h{a}=2; say %h}; say %h
a2
a1
