v		input view
args...		access specifiers

Get is the workhorse operator for extracting values from a view. The type of the result depends on which arguments are specified, in particular which column is being accessed.

Here is a summary of the different arguments allowed:

Get row col => extract one value

Get row * => extract one row, all columns

Get row => extract one row, include column names

Get * col => extract all rows, one column

Get * * => extract all values as a single list

Get * => extract all values as a list of lists

Get # => return the number of rows

Get @ => return the meta view

If more arguments are specified, these will be applied in order as if multiple get operators were chained together.

Note that this makes get a replacement for several other operators, such as {getcol}, {meta}, {names}, {size}, {types}, and {width}.
