de-sugaring

Hi Greg

When compiling you can supply a -Xprint:phase argument to the compiler to output the program after a certain compiler phase has completed. You can also supply this argument to the interpreter (which just uses the compiler behind the scenes).

I'm not sure the phase that you're after, but you could use -Xshow-phases to get a list and then experiment.

Sir and Dam Scalahads,

Is there a way to get the scala REPL to de-sugar forms? i'm looking for a way to see the 1-step and complete expansion of certain forms the way one used to be able to get with macroexpand and macroexpand1 in Common Lisp systems.

Best wishes,

The -print compiler option also shows you everything desugared.
