Multi-dimensional arrays, tutorial?

[Björnke von Gierke]

Jim, your folder analogy is not correct, as this works fine:

put "mex" into foo["bar"]["tex"]
put foo["bar"]["tex"]
--yields: mex

With multiple arrays, I always run into conceptual problems (aka. brain pain) because in the example above:

foo is an array (has keys)
foo["bar"] is also an array and has keys
foo["bar"]["tex"] is not an array and contains text ("mex") --damn

I have written an advanced tutorial (read: confusing) on various uses for multidimensional arrays when having tab delimited data:
