type.named_argument_unsupported

Callable does not take named arguments.

Area 3, Logic; not declinable; the next step is usually the agent's.

example
type Number = Int {}function add(left: Number, right: Number) -> Number {    return Number(left + right)}function three() -> Number {    return add(left: 1, right: 2)}
jadpo checkcheck failed: 1 error, 1 file

error add takes its arguments in order, without names

--> main.jadpo:8:16

  |8 |     return add(left: 1, right: 2)  |                ^^^^ named
reason
Named arguments exist only for standard-library operations; your own callables are called positionally, in the order of their parameters.
next
Remove the argument names (agent)
