ServletModuleBuilder uses "with" as part of the EDSL which causing issues with Scala

[GoogleCodeExporter]

In Scala 'with' is a keyword so invoking a method called 'with' won't work.
Would it be possible to add a set of extra methods named 'by'? That way
Scala users would be able to use the new servlet extension without any hackery.

I'm not a fan of constraining our language to permit the keywords in other JVM 
languages. There's a lot of words 
we use: to, in, and bind.

What kinds of hacks are necessary? It seems like this would be a fairly common 
problem in Scala...

something like this fixes it in the scala side:

@limpbizkit - seems with is the only clash with scala I've found with guice. 
'with' in scala is kinda like 
'implements' but for traits. 

@fede that seems to barf on scala 2.8.0 beta 1....

@fede - bizarre - the error I posted only seems to occur if you use `with` (or 
your by() method) inside a loop! 
Very odd - I raised a Scala compiler issue...

In summary, this workaround seems to work fine for me in scala...

serve("foo").`with`(classOf[FooServlet])
