I have a long function which produces `list-of-lists` :
((Sun 21 li 13 201.2139410)
(Moon 11 le 21 131.3457459)
..)
before entering a list comprehension (simplified for brevity):
(defn calc ...
(let [ .
...
list-of-lists (map #(rest (first %))
for macro expects each pair to be either binding-form/collection-expr or
one of known modifiers (:let, :when, :while).
Here:
plan (keyword (first l))
you give a pair of binding-form and keyword (which is really impossible to
iterate over).
If you meant let-binding for plan, dec, min and long,

Thread-first macro - will insert list-of-lists as first argument for map,
which is definitely not what you expect. Use threading-last - instead.

I've never quite understood the distinction other than - does
everything top to bottom and - does the
`-` inserts its first argument into the second position of the next
argument, and so on, so
(- []
(conj 1)
(conj 2))
Turns into
(conj (conj [] 1) 2)
`-` inserts its first argument into the LAST position of the next
argument, and so on, so
(- 1
(conj [2])
(conj [3]))
Turns into
(conj
