Recently I found, in The Literary Nest, the mathy poem, "Functional" by retired math teacher and active poet Carol Dorf. Dorf's poem is a pantoum -- and the interplay of math terminology with repeated lines, gives us some new thoughts to think. Enjoy!
Functional by Carol Dorf
Fanatic is the word of the day.
The domain of the function is the set of inputs.
How did the programmer know in advance?
The range is the set of outputs.
