natpryce: could you show your identifiers?

They were tests.  Like…

```
fun `a test with spaces in its name`() { .. }
```

and

```
fun `a test with spaces, and a comma`() { ... }
```

worse, IntellJ offers a refactoring to convert camelCaseNames to ``backticks and spaces``, but that refactoring stops the code compiling on the JS target

please file an issue about wrong IDEA’s suggestion

IntelliJ’s suggestion is not a problem.  In JS the test gets compiled to a QUnit test, like this:

```
  QUnit.test('ByteArraySpliceTest.can_mutate_the_replaced_bytes', function () {
    (new ByteArraySpliceTest()).can_mutate_the_replaced_bytes();
  });

```

and it’s fine for the test name to contain spaces.

how do you get it if members with spaces prohibited?

Exactly!  Tests are handled as a special case by the compiler. It should allow spaces in test function names.  And then IntelliJ’s refactoring (which only applies to tests) would be appropriate.
