Vim Macro on Every Line of Visual Selection

I'd like to run a macro on every line in a selection, rather than totalling up the number of lines in my head. For instance, I might write a macro to transform:

Last, First

Into

First Last

and I'd like it to run on all these lines:

Stewart, John 
Pumpkin, Freddy
Mai, Stefan
...

Any ideas Vim gurus?

EDIT: This is just an example, obviously this is trivialy regexable, but there are other instances that come up that aren't quite so easy that I'd prefer to use macros.

You can add the function below to your ~/.vimrc or simply copy it on your browser and running :@+ 

fun! RunMacroOverSelection(macroname)
    execute "'<,'>normal @". a:macroname
endfun
com -nargs=1 Rover :call RunMacroOverSelection(<f-args>)
nnoremap <leader>r :Rover<space>

The advantage is that you can apply any macro on the visual selection. You need to give the macro letter as argument, like:

:Rover a
