`naming.folded_collision`

Two names fold to the same file name.

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

Two names that become the same file name are an error, except a type beside the action, query or function in its own file (CreateTodo in create_todo.jadpo):

example

type DueDate = CalendarDate {}

example

function due_date(due: DueDate) -> DueDate {    return due}

text

error: `due_date` and `DueDate` share a file name --> main.jadpo:1:10  |1 | function due_date(due: DueDate) -> DueDate {  |          ^^^^^^^^ also `due_date.jadpo`  reason: Both names become `due_date.jadpo`, so a search for one finds the other; `DueDate` is a type in `due.jadpo`.  next: Rename one of them so their file names differ (agent)  rule: naming.folded_collision  help: https://jadpo.dev/docs/errors/naming.folded_collisioncheck failed: 1 error, 2 files
