An enclosed array is a [[scalar]], which is subject to [[scalar extension]]. This can be used to simulate [[Outer Product|outer product]] by a [[scalar function]] or one-sided [[Each]] (pair the entire right argument with each element of the left argument, or vice versa). A notable application of this behavior is the "chipmunk idiom" <source lang=apl inline>X⊃¨⊂Y</source>, which simulates <source lang=apl inline>Y[X]</source> for (possibly nested) [[vector]] Y and simple X. | An enclosed array is a [[scalar]], which is subject to [[scalar extension]].
