`syntax.named_argument_equals`

Named argument written with =.

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

A named argument is name: value.

example

type ItemPrice = Decimal {    scale: 2    min: 0.00}type People = Int {    min: 1}function share(total: ItemPrice, people: People) -> ItemPrice {    return ItemPrice(decimal.divide(total, people, rounding = Rounding.half_even))}

error Jadpo names an argument with :, not =

--> main.jadpo:11:61

   |11 |     return ItemPrice(decimal.divide(total, people, rounding = Rounding.half_even))   |                                                             ^ write `:`

reason: name = value names an argument in Python, Kotlin and C#; Jadpo writes name: value.
next: Use : instead of = (agent)
