I tend to agree that ? looks like "if then" when what we really want is some sort of coalescing, or "if not then".

foo ?? { bar }

foo ?/ { bar }

foo ?: { bar }

foo ?> { bar }

foo ||> { bar }

Im not sure I like the idea at all though. It seems like a hack around a pretty explicit design choice. Although I do tend to agree the error handling boilerplate is kind of annoying.
