How to replicate error:

This ain file should output connection headers to stderr and print a json to stdout.

[Host]
http://localhost:3000/places

[Headers]
Content-Type: application/json

[Backend]
curl

[BackendOptions]
-sS -D /dev/stderr

But what actually happen is that stderr (the headers) are printed on stdout.

You can check this by running this line and reviewing the content of headers.txt file:

ain the_code_provided.ain 2>headers.txt

Why I consider that this should not be like this?

1. Because as user I expect to be printed to stderr
2. Because stderr could be used for logging and will allow to do this with the provided example :

ain the_code_provided.ain | jq

And don't make crash the jq parser.

Thanks in advanced!
