Hi!
How to call function with arguments from async()?
For example, trying to pass variable "conn" of type "Connection":
auto r = async((Connection c){ return c.waitEndOf(type, timeout); }, conn);causes error:
../../.dub/packages/vibe-d-0.7.27/source/vibe/core/concurrency.d(1140,23): Error: template vibe.core.core.runTask cannot deduce function from argument types !()(void function(FreeListRef!(shared(bool), true) dst, bool delegate(Connection) @safe callable, Connection param2) @system, FreeListRef!(shared(bool), true), bool delegate(Connection) @safe, Connection), candidates are:

I've fixed the error on master: a8faddf
The problem was that the non-shared (using runTask for concurrency) path wasn't tested, only the shared one (using runWorkerTask).
