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}
text
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)  rule: syntax.expected_expression  help: https://jadpo.dev/docs/errors/syntax.expected_expressioncheck failed: 1 error, 1 file
