Mutability and make-immutable-hasheq

[Anonymer]

Why does the make-immutable-hasheq appear to make a MUTABLE hash when
'immutable' is in its name?

(hash-ref (hash-set (make-immutable-hasheq (list (list 1 50))) 1 600)
1)

[Jay McCarthy]

hash-set returns a new hash table. This only works for immutable tables.

hash-set! imperatively modifies an old hash table. This only works for
mutable tables.

PS, WIfi on a plane is so cool
