Attempt to find my way back to the point
where the digression regarding dependency-injection started.
As it turns out, this was a valuable digression, since we can rid ourselves
from lots of ad-hoc functionality, which basically does in a shitty way
what DependencyFactory now provides as standard solution
FIRST STEP is to expose the Navigator as generic "LocationQuery" service
through lib::Depend<LocationQuery>
decided to add a very specific preprocessing here, to make the DSL notation more natural.
My guess is that most people won't spot the presence of this tiny bit of magic,
and it would be way more surprising to have rules like
UICoord::currentWindow().panel("viewer").create()
fail in most cases, simply because there is a wildcard on the perspective
and the panel viewer does not (yet) exist. In such a case, we now turn the
perspective into a "existential quantified" wildcard, which is treated as if
the actually existing element was written explicitly into the pattern.
...actually just more test coverage,
the feature is already implemented.
What *could* be done though is to inject that UIC_ELIDED marker
on missing perspective specs in create clauses automatically...
This looks like YAGNI, and it would be non trivial to implement.
But since the feature looks important for slick UI behaviour,
I've made a new ticket and leave it for now
with the exception of some special situations,
which require additional features from the engine,
especially binding-on-context
Not sure though if I'll implement these or say YAGNI
