Hi Guix,

Our documentation mentions that snippets can be a gexp. Sadly, this is

rarely possible in practice because it seems to be prone to top-level

dependency cycles between the modules.

The solution would be to turn the snippet field into a thunked field,

and measure what is the incurred performance penalty.

Thanks,

Maxim
