I'm not an expert on Math::BigInt, but it seems to create objects and by copying you are always accessing the same instance.

And when searching for a clone method I found this in the documentation

$y = $x->copy();         # make a copy (unlike $y = $x)

So maybe try this?

HTH! :)

> This behaviour can be avoided if I use the overloaded ++ operator instead of the binc() method call:

Well you could "overload" assignments via tie, to always do a copy ...

see overload#Overloadable Operations:

> Simple assignment is not overloadable (the = key is used for the "Copy Constructor"). Perl does have a way to make assignments to an object do whatever you want, but this involves using tie(), not overload - see "tie" in perlfunc and the "COOKBOOK" examples below.
