Yes you are right, I will edit.
Let’s say we have variable “signal” depending on variable “frequency”.
With the proposed syntax, you could do something like:
(signal/frequency)[2:3]
or
signal[2:3]/frequency[2:3]
What I propose is:
s = signal[2:3]
s/get_dependencies(s, “frequency”)
Now, that I think about it, this does not seem too usefull, as long as the dependencies are always bound to variables.
