I’m noticing
```Runtime exception  Handler dispatch failed; nested exception is java.lang.NoSuchMethodError: 'java.lang.Object arrow.core.Either$Right.getB()'```

When trying to consume older versions of arrow across different projects

specifically when binding inside of an either computations

Hi Cody, is it possible that you may have two different versions of Arrow in the classpath? That parameter changed and it’s no longer called `b` , it’s now called `value` <https://github.com/arrow-kt/arrow/blob/a68a41cb874c031490fdb3b0adda3ea34d53bf45/arrow-libs/core/arrow-core/src/main/kotlin/arrow/core/Either.kt#L924>
