Comment (by kini):
You might want to put this question to sage-devel if you haven't already.
I think there might be people on both sides of the argument.
On the one hand I agree that setting a variable explicitly to its default
value should be the same as not setting it at all. On the other hand, I
feel like I'd want a separate ccache directory for Sage because I would
like all Sage artifacts to be segregated from other stuff on my system, as
they currently are by default. Currently, Sage will never modify anything
outside its directory except `/tmp` and `$DOT_SAGE` unless you
specifically write code that does so (right?). Not having a separate Sage
ccache directory would add `~/.ccache` to the list.
A compromise/workaround would be to, say, symlink `~/.sage/ccache` to
`~/.ccache` manually if you want to share caches. Is this too much of a
burden, do you think, Jeroen? The SPKG installer could print a message
about this possibility, or something.
