templates in nested structs

[georgfaust]

templates are very useful to avoid redundancy

foo: [F=_]: {f: F}
foo: test: {}

but how can I use a template in different levels of a nested struct?
this will not match the template:

nested: foo: test: {} 

the template has to match the complete path:

nested: bar: [B=_]: {b: B}
nested: bar: test: {}

Is there a way to write templates that can be used in any level of a nested struct?

foobar: test: {}
nested: foobar: test: {}
nested: deep: foobar: test: {}

I assume this is a follow-up to #1725?

If so, I'm further assuming you want to constrain the value of the field f to be the path from the root level?

If so, this is not currently possible. But I've raised #165 (comment) as a discussion point in the query proposal.

I do not yet see how this could help in building a path/ID, but it may.

I give you a real world example, why I think this could be generally useful.

Say we have this, floor and part both can have rooms.

floor: [Name=_]: {name: Name}
part: [Name=_]: {name: Name}

floor: basement: room: r1: {}
part: pool: room: r1: {}

For the template to match I have to add:

floor: [_]: room: [Name=_]: {name: Name}
part: [_]: room: [Name=_]: {name: Name}

instead of just

room: [Name=_]: {name: Name}

Yes, as I've mentioned elsewhere, CUE does not have this concept of "path from the root to the current value"
