It will be tricky not to say more. We will need to store the call after we
finish analyzing the block. The tricky part is that technically it might not
have any "calls", but simply escapes.
If one day we track aliases of our parameters (and the capturing block is an
alias), then such blocks might be called multiple times on different paths and
we'll need to report the call site of the block for sure.
