v input view name command name
As create a command alias for v which can be used wherever the {view} command itself is used. The view and command will exist until deleted.
This is useful to avoid view shimmering, such as with arguments of the Tk "bind" command. By passing a command instead, shimmering can be avoided.
Example:set v [view A def {1 2 3}]
view $v as abc
abc reverse
A 0 3 1 2 2 1
