unit testing improperly ignores test funs that take args

[jbclements]

First bug report submitted using github: apologies in advance for any #githubfail :

It appears to me that the unit testing framework silently ignores functions marked #[test] that accept an argument.

Here's the file:

extern mod std;

#[test]
fn boozle(t :int) -> int {
  return 9;
}

fn main() {
  io::println("abc");
}

here's the transcript of running this:

jclements-09740:tmp clements$ rustc --test ./badtest.rs -o badtest
./badtest.rs:4:10: 4:13 warning: unused variable: `t`
./badtest.rs:4 fn boozle(t :int) -> int {
                         ^~~
warning: no debug symbols in executable (-arch x86_64)
jclements-09740:tmp clements$ ./badtest

running 0 tests

result: ok. 0 passed; 0 failed; 0 ignored

jclements-09740:tmp clements$ 

I would have expected either a compile-time error or a failed test. A compile-time error, really.

Indeed; we are already issuing a fatal error when someone tries to insert an unsafe function, so other kinds of mismatches seem plausible to me. I think all of the relevant code here is contained within librustc/front/test.rs

just a bug, de-milestoning.
