Immutability is important in FP, lots of functional languages don't even have a var-keyword - they don't deal with values in the sense that oop or imperative languages do.

(Instead, they just functionally transform shallow copies of input data, iirc this paradigm is called 'data driven programming')

...so, yeah, "no values" relative to the amount of words used in FP. The pun needs a bit of a stretch, but I'd take it ¯\_(ツ)_/¯
