You mean like

	'[1,2,3]'.__len__()

That gets you the length of the string, which is what one would 
expect, calling the __len__() method on a string.  The same works 
for an array:

	[1,2,3].__len__()

If you want to convert the string to the thing it's representing, 
you can use the eval() function:

	eval('[1,2,3]').__len__()

All very straightforward.
