Package: pari-stable

Version: 2.7.2 and probably others

In section 2.9.3 of the user's guide, the following function is defined:

histlast(n) = vector(n, i, eval(Str("%", %#-i+1)))

which does not work as described (or at all, really). For example, I get

when the previous history entry was a t_CLOSURE. (It's interpreting "%-1" as subtracting 1 from the last history entry, rather than the history entry number -1.)

I'm not sure if there's a way to do what the script is doing, or if the example should simply be removed. The documentation itself dates from 2005:

I have not tried to dig up old copies of gp to see when this actually broke (or if it ever worked, for that matter).
