Component/s: Package Manager
- OS X 10.11.4
- Run $ swift build --init library in "20160412" directory.
- Run $ swift build.
- The following error has occured.
It occurs when package's name or module's name consists of figures only.
Even if I miss a naming rule for Swift 3.0, I think this error should been prevented when running $ swift build --init.
For your information, it's not necessary for me to support a name consisted of figures only. I just tried.
