Difference between EN and AN (Re: Follow-up to Monday's discussion of digits)

According to my stability calculator:

the string "L L AN" is unstable according to -bidi, because in the 
context CS L L AN CS R (left-to-right context), it resequences in the 
order 1 2 3 6 5 4 , or CS L L R CS AN.

Thus, the label "ab<arabic 1>", followed by a label containing "<arabic 
letter>", will exhibit surprising behaviour - the number will jump over 
the dot.

the string "L L EN" exhibits no such behaviour.

I think that's the reason why -bidi currently prohibits mixing L with AN.
