[perl #77072] [BUG] @a[*] does not work as slice of all indexes

[Patrick R. Michaud via RT]

Now fixed in fca2d3.  There's already a spectest for the test, but I'm
unable to commit spectest changes at the moment so I'll leave the ticket
open for someone else to close.

I also fixed .{*} in this patch,   it probably needs tests as well.
