Yes invisible might be better language.

Yes, this is indeed misleading.

Transparent suggests inspectable. For instance, Wikipedia says:

transparency [means] operating in such a way that it is easy for others to see what actions are performed.

Also, when thinking of transparent vs. opaque data types:

In computer science, an opaque data type is a data type whose concrete data structure is not defined in an interface. This enforces information hiding, since its values can only be manipulated by calling subroutines that have access to the missing information. The concrete representation of the type is hidden from its users, and the visible implementation is incomplete. A data type whose representation is visible is called transparent.

same grammar fix as #239 here, for ref

Note:
I am currently working on a new tool with clear data structures and parsing separated from logic, so I'm checking the PRs here to see what else I can integrate; see
