36 :: problem with cross module import

  Hi,

  As an experiment, I currently port the neko virtual machine from C to nimrod. I now have the problem that I need several procs from one module in another and vice versa. To do this I use following scheme:

  
  # mod1
  
  proc p1*()
  ...
  import mod2
  
  proc p1*()=
    p2()
  
  #mod2
  
  proc p2*()
  
  import mod1
  
  proc p2*()=
    p1()
  
  Run

  but I get an error: internal error: still forwarded: test1

  Is there an easy solution other than throwing all in on module or split it up to include files ?

  Awesome.

  but I get an error: internal error: still forwarded: test1

  Ugh, internal errors are bugs, so please submit a bug report ... I'm however not suprised it doesn't work ... It's been years since I tested this feature and apparently not part of the test suite ...

  No... :-/ Well you can rethink your design and get rid of the cycle in your dependencies. For some particularly nasty dependencies in the compiler itself I used proc vars as a workaround.
