[Nipy-devel] more on the slice/list of slices example

[Jonathan Taylor]

i svn up'ed the code and now i don't get the error message, but it 
doesn't seem
that it is actually type checking the list of elements as traits does, 
i.e. it doesn't choke when i set it to a list value of ['abc', 45].. is 
it supposed to?

is it possible to force it to typecheck list elements (i.e. to make it 
only accept a slice or a list of slices) with a different "implements=" 
statement?  is this not a desirable feature for some reason?
