There are a small number of places in the code where FIXMEs reference
radar numbers. Is it possible for the important details from these
radars to be put into publicly visible Github issues to be tracked and
referenced by the open source community?

Hi Joe,

Definitely! If you see a particular one that you want to know more
about, please email swift-dev, and we will create an equivalent issue
on bugs.swift.org. Migrating all radar references to bugs.swift.org
would take a lot of work though, so we prefer the lazy evaluation
approach.

Hi,

If you're looking for a starter project in the frontend area (parser
in this case), here is one.

https://bugs.swift.org/browse/SR-2

This code should be accepted, but it is rejected now:

switch 10 {
  case 10:
    break
#if FOO
  case 20:
    break
#endif
}

$ swiftc /tmp/a.swift
/tmp/a.swift:5:3: error: 'case' label can only appear inside a
'switch' statement
  case 20:
  ^

Could you post the actual error message, and SHA1 hashes of the files?

Note that I'm already working on this part. The Swift runtime needs to
provide low-level reflection interfaces that allow the standard library to
implement Mirror without depending on private runtime ABI.

I will take a look at this one.

Subject: [swift-dev] Starter project: Port Swift to RHEL 7 / CentOS 7
        / Scientific Linux 7

Hi,

RHEL 7 and CentOS 7 are widely used as server operating systems, and
porting Swift to these distributions would benefit many community
members. It should be relatively easy to do, since RHEL 7 is
fundamentally another Linux system that uses the same basic libraries
as other Linux ports we already (Glibc, libstdc++), and the library
versions are more or less recent.

This project is an easy way to become familiar with the build system,
and various components of the project, and to start contributing!

    I am interested to take up this project but I don't have any such
experience of porting.
Could you please provide how do I start ?
- Vivek
