OK - I'm starting to have ideas above my station now
In sizes example on pages 49/50
numbers is set to accept multiple inputs
Snap seems to automagically convert that to a list and processes it within the script as a list
But then later, we have to drop the next list onto the arrowheads so that sizes doesn't get upset that it is being passed a list
But since it treats an input list as a list, couldn't it automagically detect that its being passed a list rather than the programmer having to explicitly having use the dropping onto arrowheads.
Or is the overhead too much or is there something further down the rabbit hole that needs this technique?
Or should I go back to working in 6502 machine code?
