Cannot use in/out on parameters, cannot return values

[Lucretia]

There are some issues I don't know how to work out.

1. gnatbdd copies the in out specification to the generated source. See below, I would put in String normally.

2. How do you handle return values? 'a' below?

   -- @given ^a ← tuple((\d+.\d+), (\d+.\d+), (\d+.\d+), (\d+.\d+))$
   procedure Given_A_Tuple (A : out Tuple; X, Y, Z, W : String);

Ok, so it seems you can only use procedures and not functions and you have to create local variables in the steps packages as context. This really should be documented.

I will happily look at pull requests (and very likely accept them, since I haven't done anything with this project for years)

I think this is indeed one of the drawbacks of this whole approach, the use of global variables for the tests. It would be nicer to have some notion of context somewhere, which users could extend and that would be passed to all the "@given", "@then" and "@when" procedures

From what I've seen on the Cucumber site, some languages do provide a context, I think Python is one.
