Running expr example

Hi, i tried to run the expo example by lunching the Makefile, but i got the following errors in output:

make: *** [expr] Error 1

[roop]

The first error seems to imply that you're on Swift 3.x or earlier. Can you confirm?

Citron requires Swift 4.

[roop]

To repeat: Which version of Swift are you using?

[roop]

I'm closing this under the assumption that you're using Swift 3. Please reopen if you're seeing this in Swift 4 or later.
