Hash-table name?

General

I’ve been following the topic RFC: hash table pattern matching.

The Racket Reference (4.15 Hash Tables) mentions performance differences between mutable and immutable versions.

In other languages Hash tables go by other names in other names; dictionary (Python?), associative array(Awk?) , map (Haskell?), and I’m sure others.

Why not name them for the algorithm or performance characteristics?

I’m sure this is a gap in my CS education, so please forgive my ignorance.

Best regards

IIRC, in Racket BC mutable hash are actually hash tables, but immutable hash use a different algorithm under the hood but have the same user interface.

Also, in all cases Racket hash tables are implemented based on a hash of the key.
