Yonik Seeley commented on SOLR-10682:
-------------------------------------
bq. Overlapping names will be a problem because in Streaming Expressions a name
is mapped directly to a function implementation.
Hmmm, we can't overload at all based on context or arguments currently?
I'm thinking min(field) is nicer than explicitly naming every implementation:
min_double(field), min_long(field), min_string(field), etc...
