The outer definition here is a conjunction which takes two arguments: A number (<code>m</code>) and a verb (<code>v</code>). (In the original definition, there was no v and instead that verb was defined in place.) In this outer definition, <code>a=.cocreate<nowiki>''</nowiki></code> defines a new, empty namespace <code>a</code>. Then, <code>n__a=.m#_.</code> populates the name <code>n</code> in that namespace with <code>m</code> NaN values. Finally, we curry the verb <code>v</code> with this namespace and return the derived verb.
