What you describe is pretty close to the track that DWT(2) has taken - porting SWT from Java by basically stubbing out the Java standard library and then tweaking the Java source. http://www.dsource.org/projects/dwt There's also this project, though I don't know what state it is in: http://www.dsource.org/projects/tioport 2010/7/7 Jonathan M Davis <[email protected]>: > On Wednesday 07 July 2010 21:46:01 fantasticfears wrote: >> I know Java programs can be machine-translated into SafeD from >> http://www.digitalmars.com/d/2.0/safed.html. >> But what's the difference between SafeD and Java? > > SafeD is the safe subset of D.
