Hi Cayetano,

As Liliana noted, this is the intended behavior: auto-loading of
‘manifest.scm’ happens only for interactive use.  This is to keep
non-interactive use context-independent and thereby avoid bad surprises.

Note that when ‘manifest.scm’ is auto-loaded, a message is printed; when
it’s not considered, no message is printed.  Likewise, when creating an
empty environment, a warning is printed (twice even :-)).

Any suggestions on things we might improve to avoid confusion?

Thanks,
Ludo’.
