it's not the definition, it's merely a way of saying "what it is" in a
paradigm like the C language's, to allow some implementation starting

the ability to find all references or even a specific reference to an arrow
or object at hand. in a several megabyte image file, this could be quite an
overhead or bottleneck in terms of interactivity.

ok. i can see why you're confused. what the grouping construct is good for
is merely syntactical orthogonalization of all meaning. its therefore a
completely general-purpose mechanism for isolating meaning and mechanism. i
can use it to make statements about anything, by describing a mapping, a
literal syntax structure in a language, or a database.
what i'm saying about arrow-creation is that it will always be contained
within some context, just as a message from the user to "delete all" should
never nullify the system, because the system already is limiting the user to
some context in order to ease interface problems.

i'm not sure how this relates to this case. could you explain in a more

most of it is just syntax. semantics would derive from the system of arrows
made by the user itself.
i will, though, walk through the ideas for operators in more definite terms
and give examples in a little while.

right. i'll try to fulfill you're requirements there.

yes. i would like that too, as long as i can trust you all to implement it.
