Shepherd's code is pretty normal-looking Scheme code to me, last I checked :-) I think Ludovic has also been working toward bringing it closer to their standards, e.g. deprecating the use of GOOPS. > 2.

It seems reasonable to me that the close integration of Shepherd within Guix introduces a dependency on it. > 3.

As far as I can tell, both are based on SRFI-9 records and use the same representation, or I miss the fine details from the source. --=20 Thanks, Maxim
