Yeah, it's a tough problem, and actually mathematicians don't say it as 
"operation" so often, and tends to use "operator" with some special 
connotations too (but nothing to do with 1-to-1 and onto). It's all a big 
mess. No way out but to be more verbose; or else, all agree to rely on a 
specific glossary for all that gets said on pd-list (which is not actually 
doable...).
