  - Vector / Dynamic arrays
    - "append" (vector:: append / dyn_*::append)
    - "at" (vector:: at / dyn_*::at)
      Returns a reference to the element at the given idx out of the vector/dyn_*.
    - "clear" (vector:: clear / dyn_*::clear)
      Empties the vector/dyn_*.
    - "contains" (vector:: contains / dyn_*::contains)
      Returns true if an element is equal to the given value or false if not found.
    - "count" (vector:: count / dyn_*::count)
      Returns the number of elements in the vector / dyn_*.
    - "first" (vector::first / dyn_*::first)
      Returns a reference to the first element of the vector/dyn_*.
    - "indexListOf" (vector::indexListOf / dyn_*::indexListOf)
      Returns a list of indexes at which the given value was found.
    - "indexOf" (vector::indexOf / dyn_*::indexOf)
      Returns the index of the first element which is equal to the given value. The search starts at the given index.
    - "insertAt" (vector::insertAt / dyn_*::insertAt)
    - "isEmpty" (vector::isEmpty / dyn_*::isEmpty)
      Returns true if the vector / dyn_* is empty.
    - "last" (vector::last / dyn_*::last)
      Returns a reference to the last element of the vector/dyn_*.
    - "prepend" (vector::prepend / dyn_*::prepend)
      Insets the given value as the first element of the vector/dyn_*.
    - "removeAt" (vector::removeAt / dyn_*::removeAt)
      Removes the element at given index. The vector /dyn_* has one element less after this.
    - "replaceAt" (vector::replaceAt / dyn_*::replaceAt)
      Replaces the value at the given idx position with the given value.
    - "sort" (vector::sort / dyn_*::sort)
      Sorts the array.
    - "takeAt" (vector::takeAt / dyn_*::takeAt)
      Takes the element at the given idx out of the vector/dyn_* and returns its value. The vector/dyn_* has one element less after this.
    - "takeFirst" (vector::takeFirst / dyn_*::takeFirst)
      Takes the first element out of the vector/dyn_* and returns its value. The vector/dyn_* has one element less after this.
    - "takeLast" (vector::takeLast / dyn_*::takeLast)
      Takes the last element out of the vector/dyn_* and returns its value. The vector/dyn_* has one element less after this.
    - "unique" (vector::unique / dyn_*::unique)
      Removes all duplicate elements in an array.
