Summary | conversion of error value to object still useful |
---|---|
Description |
disarm was deprecated in alpha 55, and with reason because the new approach to errors makes its original (REBOL 2) purpose superfluous however, the ability to convert an error value to the equivalent object value was useful; it is true that this conversion can be achieved by finding the binding (e.g. obj: bind? in err 'id) but since the opposite is allowed (to-error obj) why not allow its counterpart also (to-object err) the same reasoning can be held for ports, by the way |
Example code |
to object! make error! "example" |

This will be a bit problematic. Errors aren't really objects (they are more like wrappers around objects, but also include a minimal form that has no object.)
It may be possible to extract an object from an error (as you've shown in the bind example), but there are a few cases where no such object exists. |

Here's how it now works:
>> to object! make error! "example" == make object! [ code: 800 type: 'User id: 'message arg1: "example" arg2: none arg3: none near: none where: none ] >> to object! throw 1 ** Script error: invalid argument: make error! 2 |
