Hi Simon,

Thanks for the input - comments at the bottom:

I hadn't considered (or even known about) the multiple commands 
possibility. Maybe for consistency then guix system should also work the 
same way as guix package -

guix system --list-generations

This is how I tripped over this problem initially, because of course 
this doesn't work!

Doing it this way could also allow multiple actions in one line:

guix system --switch-generation ... --delete-generation ...

but I am reading into your comment that guix system does _not_ use 
SRFI-37, and therefore cannot combine actions. In other words, it would 
take more effort to implement this change?

I suppose for those of you who have been in guix for several years, this 
is no issue, since you are familiar with all the different options. to 
me, as a relative newcomer, it didn't feel so smooth. If nothing changes 
I shall not be resorting to aliases, but simply making sure I know the 
correct syntax to achieve what I want!

Best regards,
Paul
