Package: nemerle
Version: 0.9.3+dfsg-3
Severity: important
nemerle as available in unstable appears to have some serious problems
with function-objects/delegates. As A simple example: (The code is taken
from http://nemerle.org/Grok_Functionals)
0:pts/1:~/tmp% cat funs.n
class Functions {
static f (x : int) : int
{
x * 2
}
static run_funval_twice (f : int -> int, v : int) : int
{
f (f (v))
}
public static Main () : void
{
System.Console.WriteLine ("{0}", run_funval_twice (f, 3))
}
}
0:pts/1:~/tmp% ncc funs.n

If you replace the line "f (f (v))" with "v", the code compiles and runs
(but obviously doesn't do what it was intended to do)
