I keep getting this wrong, which makes me wonder why we send split: to the separator rather than the thing to be split. Is there a benefit to doing

$- split: '1969-07-20'

Because you are telling the receiver that he should split the argument.

"Hey dash, can you split this for me?"

rather than

'1969-07-20' split: $- (which somehow seems more natural to me).

Try instead '1969-07-20' splitOn: $-

"Hey collection, can you split on this?"
