Summary: regexp match problem
Description:
The following code works:

using Nemerle.Text;
def GetLanguage(path)
{
regexp match (path.ToLower())
{
| @"file-(?<language>..)\.txt" => language
| _ => "none"
}
}
System.Console.WriteLine(GetLanguage("file-fr.txt"));

but the following does not:

using Nemerle.Text;
def GetLanguage(paths)
{
mutable result;
foreach (path in paths)
{
result =
regexp match (path.ToLower())
{
| @"file-(?<language>..)\.txt" => language
| _ => "none"
}
}
result;
}
System.Console.WriteLine(GetLanguage([ "file-fr.txt" ]));

test.n|9 col 4| 13:5: error: unbound type `matchobj.Groups["language"]'
test.n|9 col 4| 13:5: error: unbound name
`matchobj.Groups["language"].ToString'

I have the same problem while implementing regexp foreach:
http://rsdn.ru/forum/message/2943448.flat.aspx#2943448

I get the similar errors:
Error: unbound type 'matchobj.Groups["_N_4560"]'
Error: unbound name 'matchobj.Groups["_N_4560"].Success'
Error: unbound type 'matchobj.Groups["x"]'
Error: unbound name 'matchobj.Groups["x"].ToString'

It works for
def s = regexp foreach(a in ["a", "b"])
{
| "a" => "a"
| "b" => "b"
| _ => "c"
}

But not for
mutable s = "";
regexp foreach(a in ["a", "b"])
{
| "a" => s = "a"
| "b" => s = "b"
| _ => s = "c"
}

Mistake:
I meant s = x instead s = "a"
