Some (BlockID blocks) -> Size ctx' -> TermStmt blocks ret ctx' -> Maybe (StmtSeq ext blocks UnitType ctx')) -> CFG ext blocks ctx ret -> CFG ext blocks ctx ret

Arguments

:: TraverseExt ext
=> (forall cin cout. Some (BlockID blocks) -> Size cout -> Stmt ext cin cout -> Maybe (StmtSeq ext blocks UnitType cout))	This is the annotation function. The resulting `StmtSeq` gets spliced in after the statement so that they can inspect the result if desired. The terminal statement is ignored.
-> (forall ctx'. Some (BlockID blocks) -> Size ctx' -> TermStmt blocks ret ctx' -> Maybe (StmtSeq ext blocks UnitType ctx'))	As above but for the final term stmt, where the annotation will be _before_ the term stmt.
-> CFG ext blocks ctx ret
-> CFG ext blocks ctx ret

This function walks through all the blocks in the CFG calling fS on each Stmt and fT on each TermStmt. These functions return a possible annotaition statement (which has access to the result of the statement, if any) along with a context diff which describes any new variables.
