Change how optional arguments are represented within the runtime #4376

Open rwkay opened 10 months ago

rwkay commented 10 months ago

Description

Currently we use -1 to denote that a function has a variable number of arguments at runtime, unfortunately this means that we cannot check that the number of arguments that are given meets the minimum requirements for a function that takes an optional number.

Instead we should use a negative number that is the minimum number required i.e. -1 would mean that it needs to have 1 or more arguments, -2 that it should have 2 or more etc. etc.

This would allow for better runtime checking.

Perhaps it could be tweaked so that -1 means "0 or more", -2 means "1 or more", -3 means "2 or more" etc.? If -1 means "1 or more" etc. then there's no way to differentiate between "exactly 0" and "0 or more", unless the datatype supports negative 0.

Is this still planned for August?
