Hi, Sean,
Arrays of arrays don't work (don't even parse) in X10 1.5. This is a
known
limitation. If you wish to create arrays of arrays, wrap the inner array
into a class. Since X10 1.5 has been unsupported for more than a year,
this is not likely to get fixed.
The "examples" directory contains both code examples and the test suite,
which has code that may or may not compile. Files that do not compile
are marked as a limitation (see the top of the source).
Arrays of arrays do work with both X10 1.7 and X10 2.0.
