comment difficulty abstracting the OptionValue pattern
This is a better answer because I only need to mention each option string once: minimal opportunity for typos.

Clever merging of Associations and works well.

comment difficulty abstracting the OptionValue pattern
An important (if very oblique) clue is in the documentation for Association: "Normal converts an Association to a list of rules." That implies that Association isn't normal, lest Normal do anything at all to it.

comment Side-effecting an array in an association?
I found out something that functional notation [...] can do and that part notation [[...]] can't do: side-effectfully add a key. Let t = <|"a"->1|>, then t[["b"]]=2 succeeds and produces 2, but t is still <|"a"->1|>. Now t["b"]=2 succeeds and produces 2, but t is now modified and equals <|"a"->1, "b"->2|>.

comment Functional-Style Partial Application and the Accumulator Pattern?
I think I see. The leak is not in the definition of partial itself, but in the definition of the function it returns.
