Description
Liana was defined as land planarians with a broad and elongated body. The cutaneous musculature is strong dorsally and weak ventrally, where it is partially sunk into the mesenchyma. The sensory border has rare and minute sensory pits restricted to the anterior tip. The copulatory apparatus has a short and blunt penis papilla and the female canal enters the genital antrum ventrally.[1]
gollark: But if it's `Nothing`, it just returns `Nothing`.
gollark: The thing which makes it monady is that you can do `x >>= f`, which in this case takes a `Maybe` x, and if it is `Just a`, passes that `a` to `f`, which then returns another `Maybe`.
gollark: Anyway, ignoring LyricLy, the bee entity: `Maybe` can be `Just x`, representing that it has an x, or `Nothing`, representing that it contains *no* x. You can do `return`/`pure`, which gives you a `Just x` for any `x`.
gollark: Or possibly binary. Something like that.
gollark: Those are different, I think it just means "Unary operator" in APL.
