Creates an array initialized from using `inits' which is a list of the form
((<index-1> <init-form-1>)
(<index-2> <init-form-2>)
...
(<index-n> <init-form-n>))
Each element indexed will be filled with the result of evaluating the
corresponding initialization form. The array returned will be just large
enough to hold the element with the maximum index.
