Hi

This works:

```scheme
(let ((ns (make-base-namespace)))
 (parameterize ((current-namespace ns))
  (namespace-require '(file "tests.rkt"))))

```

This does not:

```scheme
(let ((ns (make-base-namespace)))
 (namespace-require '(file "tests.rkt") ns))

```

require: unknown module  
module name: "E:\a-simple-interpreter\tests.rkt"

How come?   
From the docs I understand that if the first one works, the second one should work too.  
Do I misunderstand the docs?  
Thanks, Jos

I forgot to mention: DrRacket 8.3 BC, windows 10

You probably can use

```scheme
(parameterize ([current-namespace ns])
  (namespace-require '(file "tests.rkt"))
  ...)

```

to replace?

This topic has been raised before in the old mailing list: [https://www.mail-archive.com/racket-users@googlegroups.com/msg43291.html](https://www.mail-archive.com/racket-users@googlegroups.com/msg43291.html)

I also logged this as an issue in the GitHub repo: [https://github.com/racket/racket/issues/3307](https://github.com/racket/racket/issues/3307)

My understanding is the same as `mxork` from GitHub: I only know that in most situations, `current-namespace` should be adjusted. From what @mflatt said, there appears to be a legitimate use case of _not adjusting_ `current-namespace` but _adjusting_ the second argument, but I do not know what this use case actually is.
