I may have trouble understanding the full intention.... please help me:

You want to parse 

sub test_someting($tempdir) {
    # do some tests
}

[download]

And because you see the (registered) keyword "tempdir" your test system is supposed to call this test with a prepared temporary directory? 

ok(
    test_something( create_tempdir() ),
    "something",
)

[download]

Kind of a naming convention?

Did I get it right?

If yes, I could think of some alternative (and more perlish) ways to achieve this without needing to parse the signature.

PS: not sure why you call this "dependency injection" or do you plan testruns where the injected $tempdir is not a temporary dir? :)
