# set obj [ objarray_map dst_type {list_arguments body_proc} list_of_arrays
Creates a new objarray of type dst_typewhose i-element is created by evaluating the lambda function with arguments <list_arguments> and body <body_proc> on the i-element of each array in <list_of_arrays>.
e.g.
# example:
set oa1 [ objarray new_from_to intarray 2 5]
set oa2 [ objarray new_from_to intarray 6 9]
objarray_map floatarray {{x y} {expr $x + $y}} [ list $oa1 $oa2]
