This is needed to build the num crate, as a dependency of serde. The
problem is that one of the default features itself has feature
dependencies, like so:
Previously, this would have enabled "complex", "rational" and "bigint",
but not "rustc-serialize" or "rand", resulting in a build failure. With
this patch, resolution is performed recursively, and this build
succeeds.
