Editing Nial (section)

== Application of operations ==
Nial like other APL-derived languages allows the unification of binary operators and operations. Thus the below notations have the same meaning.
Note: <code>sum</code> is same as <code>+</code>

Binary operation:
 2 + 3 
 2 sum 3

Array notation:
 + [2,3]
 sum [2,3]

Strand notation:
 + 2 3
 sum 2 3

Grouped notation:
 + (2 3)
 sum (2 3)

Nial also uses transformers which are higher order functions. They use the argument operation to construct a new modified operation.

 twice is transformer f (f f) 
 twice rest [4, 5, 6, 7, 8] 
 |6 7 8
