Probably so, but I think as long as you ensure the error gets handled somewhere (rather than crashing the program) it is good tradeoff to make. That was the problem (IMHO) with unchecked exceptions in Java. You make everything an unchecked exception because constantly adding code to handle checked exceptions is annoying and verbose, but then if you don't handle the unchecked exceptions somewhere then they crash the JVM. This is where I think the Scala/Rust approach is best. The compiler can force you to handle the error somewhere but there is very little syntactic overhead if you want to ignore an error in any particular function.
