Just got it fully working. Can I ++vote for it again?

Here's another simple example:

--def_macro sort
print sort <ARGV>;

-- sort 
goibhniu
BrowserUK
Corion
antirice

BrowserUK
Corion
antirice
goibhniu
[download]

Which shows conclusively that antirice is greater than goibhniu, so:

-- promote_macro sort
Macro sort successfully promoted!
