WG1 - Core
description
(Email from Vincent Manis)
Problem: It's impossible to write a portable error handler that writes out the ''message'' and ''irritants'' that were passed to `error`.
This comes about because `error` creates an "implementation-defined object". I would assume that this hides the whole exception class hierarchy a WG2 implementation might provide. Since the ''message'' and ''irritants'' arguments to `error` are presumably living in this implementation-defined object, it should be simple enough to provide accessors to extract them, so that the above "portable error handler" can be written.
Suggestion: Add the following procedures:
`(error-object? `''object''`)`
Returns `#t` if ''object'' is something created by `error`, `#f` otherwise. Any constraints on type disjointness are up to the implementation.
`(error-object-message `''object''`)`
Returns the message of ''object''.
`(error-object-irritants `''object''`)`
Returns a list of the irritants of ''object''.
