ISTM that this {*} thing is a relatively recent addition to the langauge,

 Not really, it was added in 8.5, which was released Feb 12, 2016 [1].
Although 2016 *is* relatively recent in regards to many expect scripts.
 

since Expect has been around for a long time, and most of the scripts that
do this sort of thing were written long ago.

 Before 8.5, 'eval' was the way to perform the "splicing" that {*}
provides.
