Otherwise handling outputted arguments becomes inconsistent and problematic. Also, remember when you start adding arguments into an empty list cat, the first argument added will be just an argument until another one is added at which point it becomes a list.

Sounds good. Thank you for that, Jonathan. One thing to also think 
about, I used list cat extensively in L2Ork where I wanted to optimize 
network packet distribution by coupling a bunch of args into a single 
"send <list of args>" message and this is where list cat would group 
sometime up to several dozen arguments in a single interrupt/cycle, 
meaning it would do so recursively during the same cycle. This is a case 
we may also want to consider.

Best,

Ico
