TruffleVM.eval(Source)

[Jaroslav Tulach]

Hi.
Originally I wanted to keep TruffleVM as separated from "language implementor 
specific" Truffle APIs (like nodes, targets, etc.) as possible. That was the 
reason I used URI as identification of a file to evaluate. However since then 
I realized there is well encapsulated Source abstraction that many existing 
languages already use. It took a while but today, I am giving you 
eval(Source):

http://lafo.ssw.uni-linz.ac.at/javadoc/truffle/latest/com/oracle/truffle/api/vm/TruffleVM.html#eval-com.oracle.truffle.api.source.Source-
it replaces and unifies previous eval methods (which are now deprecated and 
will be removed before final release).  In addition to that we have a way to 
associate MIME type with a Source, which is used behind the scene to select 
the right TruffleLanguage for to be evaluated Source.
