An little off-topic discussion: I sometimes think use of English is a bit too silo-ed.

This is talking about transformers of a mathematical nature. The same term can describe an electrical component. The word itself "trans-form-er" seems to mean "A thing that changes (the shape of?) something" - this is a very vague semantic, maybe appropriate for an abstract mathematical notion, but silly for any specific thing.

It reminds me of all the vague nouns used to name OOP objects: FooManager, FooHandler, FooController, BarContext, BarInfo, BazAdapter, BazConvertor, BazTransformer; etc etc etc.
