If the desired function doesn't inspect the input then why not just use
const <<thing you want>> ?
As to the lenses part: If you use a prism and it doesn't match, then it's a
noop.

Hi,
I want to have code that produces the following result no matter if input A or B was given:
Result: { "outer" : { "inner" : "new-value" } }
A: { "outer" : { "inner" : "old-value" } }
B: {}
`json & key "outer"._Object.key "inner" .~ "new-value"` didn't work.
Is what I want even possible with lenses?
