What Robert is saying is that is valid syntax for ruby 1.9, but not for
ruby 1.8.

I don't know what "the textbook" and "the cookbook" are that you refer
to, but they were probably written for 1.9.

ruby 1.9 is a substantially different language to ruby 1.8, which you
probably wouldn't expect from the "minor" version bump.

Ditto in arrays as well as parameter lists. (Kind of interesting that
1.8.7 also gives the useless literal error.)

$ ruby -ve '[1,2,*[3,4],5]'
ruby 1.8.7 (2008-05-31 patchlevel 0) [i686-darwin9.8.0]
-e:1: syntax error, unexpected ',', expecting ']'
[1,2,*[3,4],5]
^
-e:1: warning: useless use of a literal in void context

$ ruby191 -ve 'p [1,2,*[3,4],5]'
ruby 1.9.1p376 (2009-12-07 revision 26041) [i386-darwin9.8.0]
[1, 2, 3, 4, 5]
