such a mechanism would be very useful.


Although one thing I'd like to see is a mechanism, e.g. doublealpha()  
or some extension to alpha(), to handle the perculiarities of nested 
Burmese alphabetic lists, where the consonant is doubled, so first item 
in a nested list (i.e. a list within a list) would be ကက, second item 
would be ခ ခ, the third would be ဂ ဂ, etc. I'm not sure how many other 
languages use a similar approach, but the doubling of consonants can be 
observed in official Burmese documents in nested lists.

Shan digits would be useful.
