I present Bit::Vector which has the overloaded operators addon Bit::Vector::Overload, which is to be used in place of Bit::Vector, but with all the benefits.

And just as a friendly reminder, I must point you to How to read the Friendly manual

...reserved for each element in the bit vector.

You were wanting 64 bits, so each is one bit wide. This is 32-bit perl:

$ perl -e 'vec( $foo, 63, 1) = 1; print unpack( "b64",$foo),$/'
0000000000000000000000000000000000000000000000000000000000000001

$ perl -e 'vec( $foo, 63, 1) = 1; print scalar reverse(unpack "b64",$f
+oo),$/'
1000000000000000000000000000000000000000000000000000000000000000
