This is what I tried first, the point is when you quite the enclosure, even if you use no bignum, since the variables have declared previous as bignumn any calculation using such variables previous declared as bignum will be store in variables of the same type. This make sense for perl, only a cast should allow changing the size. In addition, the physical size (SV) of a bignum seems a lot bigger than a usual NV.
