I was planning to implement a modifier that works like this:
"We have %0 %c0{1:mouse|:mice}"
i.e. a simple case statement. ("case parameter 0 in") The modifer picks an
integral argument and executes the case. It could be more complicated for
languages that, say, have different forms for 0, 1, 2, and more cases:
"%c0{0:something|1:somethingelse|2:yetanotherthing|:finaloption}"

This seems flexible enough to handle all cases. For simple s plural forms,
it's even pretty small.
"function%c0{1:|:s}"
