While initially building out unified IR, I didn't have any indexing scheme. Everything was written out in order. Consequently, if I wanted to write A before B, I had to compute A before B. One particular example of this is handling closure variables: the reader needs the list of closure variables before it can start reading the function body, so I had to write them out first, and so I had to compute them first in a separate, dedicated pass. However, that constraint went away a while ago. For example, it's now possible to replace the two-pass closure variable capture with a single pass. We just write out the function body earlier, but then wait to write out its index. I anticipate this approach will make it easier to implement dictionaries: rather than needing a separate pass to correctly recognize and handle all of the generics cases, we can just hook into the existing logic.
