As far as I understand is, it requires each component to

Now in D we use the opDot to chain components, which works
since we have UFCS.
In F# there a simply three different opDots: >>, >>= and >=>
which take care of
the adaption.
Or we could just use exceptions, which require none of that.

Right now my experience from some quick experiments with Rust
seems to indicate that it is a good sort inconvenience for
medium-to-big applications as it forces you to explicitly
consider all possible exceptional paths possible in application
without and does not add any runtime overhead.
For smaller / less important programs verbosity does seem
inconvenient in an unpleasant way indeed.
