:: String -> Int -package:hledger-lib -package:speculate -package:locators -package:Agda -package:express -package:ghc -package:string-conversions -package:safe package:base is:exact

Raises an error with a printf-specific prefix on the message string.
Like the function error, but appends a stack trace to the error message if one is available.
Convert to an Int. It is implementation-dependent what fromEnum returns when applied to a value that is too large to fit in an Int.
