I agree @inline (which will probably be an extension) in D should mean

Ignoring the impossible-to-inline cases (which in time should get

adding @inline is a few minutes of editing.
It will just bypass the cost function and if it is not possible to
inline, pop
error.
Sure, but I think you'll be very disappointed in that it isn't going to
deliver the goods.

Just bypassing cost escape, I ll try some complex cases soon after i get
phobos working.

int test() @inline // test_inl.d
