@DamienIrving I'm not sure what you think about this, but parsing
inargs
tomain
means thatmain
can't be re-used elsewhere (one of the students tried to copy things to a notebook and then run things). If we changed the pattern a bit (suggestion here but not the only way) then code re-use might be simpler (and we could documentmain
).
