User:Hyp cos/Hyper Nested Array Notation

Hyper nested array notation (HNAN) is the 6th part of the R function series. First I change some notations to make things below easier. Consider a separator - {S**...*} where S is a string and there're m asterisks, and in HNAN it's {S,,m}. The whole "double comma" is a new separator and the m is the string after it. See, asterisks disappear from now on.

An encloser for an entry is a 1-encloser. Now I define some 2-enclosers: { ____ ,,m} - there can be commas, {1,,1}'s, {0,1,,1}'s, {0,,2}'s etc. in these enclosers, so they're different from 1-enclosers.

So {0,,1} is shorthand for a comma, or the standard separator (here I say, standard 1-separator) of { ____ } for 2-encloser. {0,,2} is the standard 1-separator of { ____ ,,1} for 2-encloser, and {0,,m+1} is the standard 1-separator of { ____ ,,m} for 2-encloser.
