Summary: runtime error: lists of tuples with list elements

Initial Comment:
void main(String[] args) {
  let List<(List<byte>, String)> a = [([1,2,3], "Hello")];
  (List<byte> l1, String s1) = a[0];
}

throw: nice.tools.code.EnsureTypeProc has wrong type ([B)

The error occurs when assigning to l1 (of type List<byte>)

This bug has been fixed. The next release of the compiler will
include this correction. In the mean time, I encourage you try
the development version. It contains a version of the compiler
that fixes the bug. Please try it and reopen the bug-report if
you find any problem with it.

To know how to get an install the development version of the
compiler that fixes this bug, please read

Note that the bug has first been fixed in the CVS version, and it
might take one or two hours until the development version
includes the fix.

Thanks again for your help by submiting this bug report.

The bug is that an array nested in a another array or tuple 
doesn't get wrapped to a list.
This code gives the same error:
List<List<int>> x =  [[1,2,3]];
int i = x[0][1];

It possible to workaround this bug by assigning the inner array 
to a list first.
Your example will work if you change it to:
let List<byte> x = [1,2,3];
let List<(List<byte>, String)> a = [(x, "Hello")]; 
(List<byte> l1, String s1) = a[0];
