Comment 8 for bug 1824277

Ah, sorry, I was misunderstanding the whole thing getting the impression that writing to INPA should immediately write-through to A.

So - to clarify my understanding - the idea is that constant input links can be changed at runtime (just like CA or DB input links) and the new constant value would be used at the next record processing (just like the new CA or DB input link would be executed).

I find this behavior reasonable and useful.
Still, I would like to see things being consistent. Couldn't *all* input links work this way?
Are there applications that rely on the fact that writing a value to an input link does not have an effect?
