Another important difference is that no intermediate collections are
built. In contrast, chaining x enumeration statements #select:, #collect:,
etc. iterates x times over the collection elements and builds x-1
intermediate collections.

Hi,
indeed, transducers provided a way to achieve this, e.g.

filter: #notNil;

map: #squared;
filter: #even;
into: OrderedCollection.
But this feature is deprecated, as it was not that useful. The preferred

Hi,
is there some library that will allow me to chain select:/collect:/... via
cascade?
E.g.
#(12 7 'a' nil #(0)) query reject: #isNil; select: #isNumber; collect:
#squared; select: #even?
The point is to not have to write billion parentheses when building a more
complex query.
I imagine this
