Match allows array-port overwrite

[dorian3343]

You can overwrite a matches array port, which creates an infinite loop. I'd expect for it to throw an error.

Example:

:data -> match:data
'H' -> match:case[0] -> ('Hello, World!' -> println -> :sig)
'Q' -> match:case[0] -> ('Hello, World!' -> println -> :sig)

I would say that's normal behaviour

You're not "overwriting" you sending to the same inport from several different places i.e. you merge several flows into one

We could in theory ban this for array-inports and say like "unlike regular inport, array-inport slot can only have one source of data" but that could lead to unexpected limitations in the future

I personally would like to see this solved as a special case in linter, when we'll have it
