#to_code(tags, template) ⇒ Object

This method is vulnerable to stack-level-too-deep scenarios where >=1,200 tags are being parsed. But that scenario can be mitigated by splitting up the tags. bbtree = { :nodes => [900tags, 1000tags] }, the work for that bbtree can be split up into two passes, do the each node one at a time. I’m not coding that though, it’s pointless, just a thought though
