[Mono-list] csharp REPL scripts

[Steve Lessard]

Yes, both Miguel's solution and Ian's solution work. I pretty much understand 
why Miguel's solution works. As for Ian's solution I read the man page for env 
but it's not clear as to what env does that makes Ian's solution work. Would you 
care to share a short explanation?

Would

#!/usr/bin/env csharp

Work?
