Is it possible to VimGolf this?

# To help me importing some CSV
# Using vim (to avoid eval hell)
# can we 'easily' move from something like

legacy_venue_id,venue_name,legacy_region_id,venue_address,venue_oot,venue_db,venue_notes

# To something like 

legacy_venue_id = row[0]
venue_name = row[1]
legacy_region_id = row[2]
venue_address = row[3]
venue_oot = row[4]
venue_db = row[5]
venue_notes = row[6]

How about this?

:s/,/\r/g                  -  replace commas with newlines
<C-o>                      -  jump back to top of block
:let i=0                   -  create a variable `i`
qw                         -  start recording a macro
A{ = row[<C-r>=i<Enter>]}  -  append ` = row[i]` at end of line, using actual value of variable `i`
:let i=i+1                 -  increment variable `i`
q                          -  stop recording the macro
jV}                        -  move down one line, then select to end of block
:normal @w                 -  execute the macro on each selected line

There's a similar example in Practical Vim, tip 70, Evaluate an Iterator to Number Items in a List.

I'm sure that if you posted this example to http://vimgolf.com/ you'd get some solutions that required fewer keystrokes!
