Oh, that sounds very good to me. There is indeed a bit of contradictions 
between "empty" and "fill" but maybe not that strong if we think of 
"empty" as a "void of actual information". (Especially true when the 
fill value is nan or inf, which, as Ben just mentionned are probably the 
most commonly used fill value after zero.)

Maybe a keyword named "value" instead of "fill" may help soften the 
semantic opposition with "empty" ?

best,
Pierre
