Uploading to Maven works
Minor bug fix: special parsing of "==>" now only within << ... >> brackets; as also done in all subscript expressions.
Fixed processing << a => b ==> c >>.
This was handled as if b was a {block} so that declared vals and vars would not become visible in c.
Not tested yet.
Also removed a superfluous&distracting line from SubScriptActor.
<< ... >>: bug fix ("=>" was not accepted) and added "val sender=this.sender" in case of "==>" presence.
