Man, it feels ungrateful to report this, but it looks like in the
process of having my wish PR#13758 fulfilled, a typo snuck in to
the "NEWS" releasenotes:

    o	New as.raw() method for "tclObj" objects (wish of PR#13578).

I'm pretty sure that's a typo, and should be 13758 instead of 13578.

Perhaps "nobody cares", but I mention it for completeness.
[and thanks for the new method!]

Cheers
