I agree.

Also, since

func <$> "foo" <*> "bar"

is the lifted equivalent of

func "foo" "bar"

I find it unintuitive to read or write the logic in the opposite order.

Whether we like it or not, Haskell is fundamentally a right-to-left 
language. Or, to look at it another way, top-down corresponds to 
left-to-right, and bottom-up corresponds to right-to-left. Perhaps it 
depends on whether you're a top-down thinker (like me) or a bottom-up 
thinker. I much prefer `where` to `let`, for example.
