XO0601: name does not resolve

A variable, function, type, field, method, module, or effect name does not exist where it is used. The diagnostic suggests the nearest real names, so an API cannot be hallucinated silently. It also covers os, expect, and testing outside tests, a tuple field out of range, and result outside an ensures clause. Float.from(n) and other unknown associated functions of a numeric type called with one numeric argument get the fix Float(n): numeric conversions are calls on the type name (std.md 2.1). See core 4.3.

Example

fn f() -> Int {
  let count = 1
  coutn
}

Fix

fn f() -> Int {
  let count = 1
  count
}
