Any alphanumeric errors anywhere? Lassi Kortela 10 Aug 2020 07:11 UTC

I did a web search for `alphanumeric error codes` and got nothing except
databases. So I wouldn't worry about them. 'number and 'symbol are fine.
'sqlstate for SQLSTATE codes.

'number    exact integer or #f
'symbol    symbol or #f
'sqlstate  5-character string or #f

Missing property is the same as #f.
