syntax.unexpected_token

Something else was expected here.

Area 1, Project layout and modules; not declinable; the next step is usually the agent's.

example
type Count = Int {    min: 0}function f(x: Count -> Count {    return x}
jadpo checkcheck failed: 1 error, 1 file

error This parameter list isn't closed

--> main.jadpo:5:21

  |5 | function f(x: Count -> Count {  |                     ^^ expected `)` before `->`  |           - opened here
reason
The parameters end with ), before fails, -> or the body.
next
Add ) after Count (agent)
