I think it’s often undesirable.
Suppose you want to use ‘current-filename’ in an ‘assert’ macro, for
instance: what you want is a hint, not an absolute path, since that path
is likely to be invalid at the time you see it (for instance, it could
point to the source tree on a build machine of your distro.)
Furthermore, including absolute paths by default makes builds
non-deterministic: two users would get different binaries, just because
they built things under a different directory.
Thus, I’d rather let users call ‘canonicalize-path’ when they know what
they’re doing, and know that they actually need it.
WDYT?
Thanks,
Ludo’.
