The REPL session from London Clojure Dojo on 1st Aug 2023 helping us understand chunking and its potential gotchas.

"This is the REPL session a group of us played with at the London Clojure Dojo on
1st August 2023 with the aim of understanding chunking and its potential gotchas.")
;; Many of Clojure's core functions such as `map`, `filter`, `take` and `drop` produce
;; lazy sequences. The elements of a lazy sequence are only evaluated or "realized" as
;; needed. Although it appears each element is evaluated one at a time, since Clojure 1.1,
;; evaluation is "chunked" such that elements are evaluated 32 at a time, a performance
;; optimisation based on the fact that Clojure's immutable data structures are a so-called
;; "trie" with 32 children per node.

Find "tonal" words in English, or more accurately, heteronyms i.e. two or more words with the same spelling but different pronunciation and meaning. More specifically, this script is interested in the stresses in a pronunciation and finds many "initial-stress-derived nouns" where verbs can be turned into nouns by stressing the first syllable e.g…
from nltk.corpus import cmudict
from nltk.corpus import wordnet
def is_multi_pos(word):
"""Return True if the given word can be used as both a noun and a verb.
With a small tweak, you can find words which can also be used as an adjective, or
any combination of the above.
