A collection of helper methods to make working with Arrays a little easier.

method drop

method drop(
    Int $count,
    Bool :$all_or_nothing = Bool::False
) returns Array:D

Returns a new list without the first or last $count elements of the array depending on if count is positive or negative.

method includes

method includes(
    $x,
    Bool :$ducktyped = Bool::False
) returns Bool

Tests if the array includes the item passed in. Set ducktyped to True for ducktyped matches. For example "4" will match 4 with ducktyped matches.

method is-empty

method is-empty() returns Bool

Tests if the array is empty

method split-by

method split-by(
    Int $size,
    Bool :$only_perfect_splits = Bool::False
) returns Array

Splits a Array into an array of arrays of the specified length (or smaller). If the array is not evenly divisble then the last array will contain the remainder. If only_perfect_splits is set to True it will throw an exception if the Array is not evenly divisible by $size.

method take

method take(
    Int $count,
    Bool :$all_or_nothing = Bool::False
) returns Array:D

Take returns count is positive or negative. If there are fewer elements than $count it will return whatever is available. Set all_or_nothing to True and it will throw an exception if there are insufficient elements.

method to-hash

method to-hash(
    :$one_based = Bool::False
) returns Hash:D

creates a hash with the stringified index of each element as its key. Set one_based to True to have it start the keys at 1 instead of 0. Example: ["foo", "bar"] -> {"0"=>"foo", "1"=>"bar"}
