This is a nice example, which exposes clearly the culprits with
[declare]'s current implemtentation. Thanks for sharing.

[declare] is definitely not ready for 'intra-project' usage. However, it
still can be used as a replacement for the command line flags '-lib' and
'-path' for system-wide installed libraries and that was the use case I
initially was talking about. Instead of Pd-extended loading system-wide
installed libraries per default, those also could be loaded with
[declare -stdlib], respectively [declare -stdpath]. And those work also
inside abstractions. 

As you pointed out, [declare] still has issues. However, in the long run
it'd be the preferred way to load dependencies dynamically from the
patch instead of generally and automatically on start-up. Do we agree
here?

It was me who reported this bug back then. And it is still not fixed.
