The Quantum::Superpositions module adds two new operators to Perl: any and 
all.

Each of these operators takes a list of values (states) and superimposes 
them into a single scalar value (a superposition), which can then be 
stored in a standard scalar variable.

The any and all operators produce two distinct kinds of superposition. The 
any operator produces a disjunctive superposition, which may (notionally) 
be in any one of its states at any time, according to the needs of the 
algorithm that uses it.

In contrast, the all operator creates a conjunctive superposition, which 
is always in every one of its states simultaneously.

Superpositions are scalar values and hence can participate in arithmetic 
and logical operations just like any other type of scalar. However, when 
an operation is applied to a superposition, it is applied (notionally) in 
parallel to each of the states in that superposition.
