Extremely, if my last experience trying it (back in 2016 or so) counts. Like all good jokes, "Haskell is the world's best imperative language" contains a kernel of truth. The standard library contains rather interesting control structures that can exist only because IO actions are lazily evaluated values -- but you can also choose to ignore those for a more Java-like experience.
