I'm wrapping C code that has start/stop, init/deinit, create/destroy function
pairs that user is responsible to call

I've found that in Nim I have different flavors to handle this\:
- not handle, let the user handle it manually like in C
- defer\: propose to use defer to deinit what has ben init
- try/finally\: like defer
- wrap C type and create init and =destroy proc

what would you suggest?
