Substitute vim with something more normal, like.. python

Better sed.

Some of the edits are more complex than sed could do IMO, e.g., locating the floating block in the tree, then jumping back two times on { and cutting the whole part between { and } and placing it at the end of the file. This can be done in a single online using vim's normal mode: %g/floating_con/norm ?{<cr>nd%"_ddGA<cr>p for every floating block in the file. Don't know whether this is possible using sed... However, I am for more readable implementation when the dust settles, something, that a non-vim user could fix.
