Username5243's Array Notation

Username5243's Array Notation, also shortened to UNAN, is a notation made by wiki user Username5243. It has the format a[#]b where # is an array. It comes in multiple parts.

Parts

 * Basic array notation: hardly even an array notation! Just the expression a[c]b, which is equal to {a,b,c}, a→b→c, and a$undefined$c in BEAF, chained arrow notation, and up arrow notation respectively.
 * 2-entry array notation: takes arrays with two entries. Close equivalence with BEAF, but a slight difference due to using 0 as a terminal value rather than 1.
 * Linear array notation: takes linear arrays
 * Planar array notation: takes planar arrays
 * Dimensional array notation: takes dimensional arrays
 * Hyperdimensional array notation: takes arrays where separators can have linear arrays in them
 * Nested array notation: takes arrays that contain arrays in seperators.
 * 2-entry First-order array notation: adds a seperator called the first order comma.
 * First-order comma array notation: more with the first order comma
 * First-order dimensional array notation: adds more first order separator
