I have found in my teaching that [trigger] is a fair more complex
thing to understand than import. [trigger] has to be explained at
length, often repeatly. On the other hand, when students have tried
to use objects from libraries and found those object didn't work, two
sentences is usually enough: "that's because that object is in a
library that isn't loaded. To load it, create an object called
The hard part is the implementation, IMHO. Ideally the implementation
will make it really that easy. It's half way there, but there are
still some hard bits to sort out.
For a related reason, I also like [import] over [declare]. [declare]
has those four flags which even I can never remember which does what,
plus it is new syntax, there are few objects that have -args in them.
[import] loads a library in the way that it should be the vast
majority of the time: into the canvas-local namespace.
