(same? ..args)
  args: two or more arguments (any type)
  returns a bool

Returns #t if all of its arguments share the same identity.

Each successive pair of arguments is compared in turn. If any of the comparisons are false, the function returns early.

• Numbers and characters are compared using ==.

• #n has the same identity as #n.

• #t has the same identity as #t.

• #f has the same identity as #f.

• All other values are references. Two references share the same identity if they belong to the same primitive type, and refer to the same memory location.
