Set::Equality - Implement (==) for older Raku versions
use Set::Equality; say (1,2,3) (==) (3,1,2); # True
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.
(==) operator concepgtually coerces its parameters to
Sets 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
False it is to return. For example:
<foo bar baz> (==) %hash
True if there are 3 keys in the hash, and they are
baz, and each of these keys holds a truthy value.
