- It allows us to avoid the "default argument" idiom, in cases where we really don't want the argument, we just want to capture the value. There are a lot of functions which have their parameter list polluted by extraneous arguments that should never be used by the caller simply because that's the only way to get early binding/value capturing.
Can you actually name a few, please? I went digging earlier, and couldn't find any really good examples in the stdlib - they're mostly internal functions (underscore-prefixed) that shouldn't be being called from outside their own module anyway. Maybe this isn't as common an issue as I'd thought. ChrisA
