Znavko,

This doesn't address all points in your e-mail, but some days ago 
I too was suprised by the fact that ‘guix weather PACKAGE-SPEC’ 
didn't just do what I expected.

I'll clean up my patch to do so (mainly testing that it actually 
works for other use cases than my… two :-) and send it in.

Kind regards,

T G-R
