when does deduplication happen for IOLists…if I create a massive IOList with a bunch of macros expanding inside of each other, will there be a final pass that deduplicates binary segments?
e.g.
1. EExFun.outter() #=> [
"<div>",
EExFun.inner() #=> ["<div> some string </div>"],
"</div>"
]
2. ["<div>", "<div> some string </div>", "</div>"]
3. [ref_div_open(), [ref_div_open(), "some string", ref_div_close()], ref_div_close()]
