I'm getting an ICE with the attached code (reduced by the amazing DustMite). 
It has to do with building a delegate literal.  I'm working on building a mock
objects framework inspired by Mockito.  DustMite reduced the code enough that
it's a bit nonsensical in the attachment, but it does reveal the error.

Found in DMD 2.060 on Mac OSX Mountain Lion.

Further manual reduction:


template TypeTuple(TList...) {
    alias TList TypeTuple;
}
void main() {
    alias TypeTuple!(int) Foo;
    int bar;
    Foo args = cast(Foo)bar;
}

https://github.com/D-Programming-Language/dmd/pull/1120

Current dmd doesn't detect invalid casting in front-end. I think this is one of
the big issue.
