If you iterate over a table value that could also be '`nil`', you get a better explanation in the error message: If you iterate over a table value that could also be `nil`, you get a better explanation in the error message:

Previously it was "`Cannot call non-function {number}?`" which was confusing. Previously it was `Cannot call non-function {number}?` which was confusing.
And speaking of confusing, some of you might have seen an error like "`Type 'string' could not be converted into 'string'`". And speaking of confusing, some of you might have seen an error like `Type 'string' could not be converted into 'string'`.
This was caused by Luau having both a primitive type '`string`' and a table type coming from '`string`' library. Since the way you can get the type of the '`string`' library table is by using '`typeof(string)`', the updated error message will mirror that and report "`Type 'string' could not be converted into 'typeof(string)'`."

## Analysis improvements ## Analysis improvements
For better inference, we updated definition of '`Enum.SomeEnumType:GetEnumItems()`' to return '`{Enum.SomeEnumType}`' instead of common '`{EnumItem}`' and the return type of '`next`' function now includes the possibility of key being '`nil`.' For better inference, we updated definition of `Enum.SomeType:GetEnumItems()` to return `{Enum.SomeType}` instead of common `{EnumItem}` and the return type of `next` function now includes the possibility of key being `nil`.
If you use '`and`' operator on non-boolean values, '`boolean`' type will no longer be added by the type inference: If you use `and` operator on non-boolean values, `boolean` type will no longer be added by the type inference:
