80 character column limits in code are a legacy from 80 column text displays which are a legacy of IBM's 80 column punch cards which are a legacy of Roman chariots which had two side-by-side 40 column horses
ok maybe that last bit is a bit silly but it's no sillier than using a nearly 100 year old punch card standard on today's wide screen monitors
@dotjayne This gives me an idea for a new syntax rule for esolangs: "Any line longer than 80 chars is a comment, regardless of content."
@kittylyst @dotjayne but this means _all_ comments have to be long… excellent!
