Description Stone 2015-01-24 19:11:35 UTC
This is a question not a bug regarding the csharp REPL.

Currently Mono.CSharp does not support loose functions but supports variables with function expressions. 

So this is valid:
Func<int, int, int> Foo = delegate (int a, int b) { return a + b; }

but not:
public int Foo(int a, int b) { return a + b; }

Loose functions would be something I would be interested in implementing. Loose functions are supported by Roslyn and would be great if Mono could support this as well.

So before I start looking into this I need to ask if this is something that is desired (part of the mono roadmap) and if you would you accept a PR that implemented this feature? 

Because this is not currently supported I suspect that adding this feature is not straight forward.  So I would also be interested to know where the main issues lie.

Cheers,
Stone.

We'd accept such PR if you don't break any existing tests. I think someone tried to implement it already but it didn't go anywhere. I can see there will most likely be issues at grammar level in our parser.
