syntax.expected_expression

Expected a value.

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

A variable is given its value on the line that declares it:

example
type Count = Int {    min: 0}function doubled(count: Count) -> Count {    var result: Count =    return result}
jadpo checkcheck failed: 1 error, 1 file

error result has no value

--> main.jadpo:6:23

  |6 |     var result: Count =  |                       ^ expected a value after `=`
reason
A variable is given its value on the line that declares it: var name: Type = value.
next
Write result's value after = (agent)
