Sorry to be slow. Naive questions.

Do you mean the issue comes from who expand '~' (user vs sudo)?
Or do you mean refer to subfolder named '~, i.e., $HOME/foo/~/bar?

I should miss a point... about what is less or more inconsistent. :-)
Because it seems more based on conventions than on consistent inconsistencies.

About expansion, is it not the same question with
'--load-path=$HOME/path/to/' vs '-L $HOME/path/to/'?
About naming, is it possible to create a folder named '~' directly in $HOME?

Well, I am surely not enough skilled to have an opinion but I have
learnt something. :-)

The fact that Guile does not have a built-in ``expand-tilde`` is a
strong indication to not do it. ;-)


Cheers,
