Feel free to make this one-line change on your own clone if it will be much faster and make v0.9

import "path"

a: path.IsAbs("/foo")
a: path.IsAbs("/foo", "unix")
b: path.Split("/a/b/c")
b: path.Split("/a/b/c", "unix")
c: path.Rel("/a/b/c", "/a/b")
d: path.Match("/a/b/c", "/a")

// Expected way to use
// e1: too many arguments in call to path.Match (have 3, want 2)
// e1: path.Match("foo.cue", "*.cue", "unix")

// so remove os...?
// cannot use "*.cue" as *"unix" | "windows" | "plan9" | "aix" | "android" | ...
// e2: path.Match("foo.cue", "*.cue")

// is this a constraint only?
// error in call to path.Match: runtime error: index out of range [2] with length 2
// e3: "foo.cue" & path.Match("*.cue", "unix")

Thanks! This would need tests, and for you to sign off the commit. As it stands, it cannot really be reviewed nor merged, so this will have to wait until v0.9.1.

Meant to mark as "changes requested".

Converting to an issue so the CUE team can fix this

#3203

I've also signed the DCO previously, not sure why GH is not detecting it

DCO, i.e. a signed-off-by trailer, has to be added to every commit to be merged. I'll continue over on Noam's patch.
