  # NAME
  
  Set::Equality - Implement (==) for older Raku versions
  
  # SYNOPSIS
  
  ```
  use Set::Equality;
  
  say (1,2,3) (==) (3,1,2);  # True
  
  ```
  
  # DESCRIPTION
  
  The `Set::Equality` module implements the `(==)` operator (and its unicode version `≡`, and its counterpart `≢`) for versions of Raku **before** the 2020.06 Rakudo compiler release. Its implementation and tests are identical to the ones from Rakudo 2020.06 and later.
  
  On versions of Rakudo that already implement the `(==)` operator and its friends, loading this module is basically a no-op.
  
  The `(==)` operator conceptually coerces its parameters to `Set`s for non-`QuantHash` types. So:
  
  ```
  (1,2,3) (==) (3,1,2)
  
  ```
  
  is conceptually the same as:
  
  ```
  (1,2,3).Set eqv (3,1,2).Set
  
  ```
  
  It will however actually do as little actual coercion as possible to provide the `True` or `False` it is to return. For example:
  
  ```
  <foo bar baz> (==) %hash
  
  ```
  
  will return `True` if there are 3 keys in the hash, and they are `foo`, `bar` and `baz`, and each of these keys holds a truthy value.
