This solution looks very ugly to me. Catching 'error's is debugging, but parser failure is kind of exception handling. I guess, the errors you want to catch are caused by non-supported fail method, right? Can't you use a monad transformer like explicit-exception:Synchronous.Exception or transformers:ErrorT around the Binary parser?
Alexey already replied, but after looking at the way Binary processes parser errors I came to the same conclusion: it is by design that it falls hard when data cannot be deserialized (btw makes sense in many cases, but not in mine). I am beginning to realize that probably (de)serializing lazy structures is not a good idea at all since such structure may be consumed in pure code, and such parser errors are hidden inside, and may "fire" at any moment. Any complications to the binary parser will bring performance penalty. Or weird solutions like mine are needed. Thanks. -- Dimitry Golubovsky Anywhere on the Web
