Maybe it can be change later.
Indeed, thank you for diagnosing this. Originally we chose to cast bin to str as hex dump because it was only used in stick tables. But now that we support other storage and usages, it becomes less and less natural. I think we'll change this before the final release so that bin automatically casts to str as-is and we'll add a "tohex" converter for people who want to explicitly convert a bin to an hex string.
