What I am about to raise, I do so more out of wanting someone to educate me
than disagreeing for the sake of. The *that syntax shown below is unfamiliar
to me outside the context of referencing a filehandle in a subroutine params
list, where it is optional (ie., &some_sub(*STDIN)). *that reminds me an
awful lot of a C pointer, however. Can someone clear this up for me?
I found the following in the Camel 3rd edition, page 257, which, though I may
be wrong, looks like it does what is requested?
@reflist = \(@x); #interpolate array, then get refs
which looks an awful lot like
@array2 = \(@array1);
