→# to an index arrays, etc
Once arrayfied, the function can take arrays as arguments, and for each of the cartesian product of the parameters, a result will be computed. For example, once arrayfied, v(1..2,3..4,1..10) will compute the value for v for each combination of the three parameter arrays.

==# to split strings==
# splits strings into arrays.
If numbers are provided on the right of #, then splits can be done in a pattern. If regular expressions are provided on the right, the splits will be based on the regular expression.

"this"# // Splits this to four separate elements, t, h, i and s.
"this"#[3,3] // Splits this to separate elements, of size 3, 3, etc.

==# to an index arrays, etc==
# can be used to index arrays, as below. If the right argument is an array, it will extract all elements represented by the indices on the right. If a multi-dimensional index is required, provide a subarray, such as [[2,3]] instead of [2,3]. To get the length of elements along a particular dimension, use the notation nd (For example, 1d to extract the size along the 1st dimension).
