I didn't think it belonged to Statistics, but maybe it does.
When I try to describe it, there's the idea of producing a "score" or a
"summary" for a collection of data points (where the data is nothing
more than: "we have a collection of so many 'x', 'y' and 'z').
Here's another example of what the module allows:
# grey
%red >= 11/36, %green >= 11/36, %blue >= 11/36: grey;
# secondary
blue > 0, green / blue > 33/36, green / blue < 36/33: cyan;
red > 0, blue / red > 33/36, blue / red < 36/33: magenta;
green > 0, red / green > 33/36, red / green < 36/33: yellow;
# primary
%red >= 50%: red;
%blue >= 50%: blue;
%green >= 50%: green;
# whatever
unknown;
which seemed to properly match my perception when used to categorize
random RGB triplets (with a little less than 30% of 'unknown', though).
Mmm, maybe a better word than "score" or "summary" is "category".
So what about something along the lines of Data::Categorize?
(although Data:: is a prefix that usually adds no information)
