+** TODO native x86 backend
+** TODO fasl/image files
+** TODO shared stack on EVAL
+   Arguably a bug, at the moment we create a new stack on every EVAL
+   (which includes every macro definition, and in particular every
+   call to let-syntax that a macro may expand into - I'm looking at
+   you, (chibi loop)).
+
+* compiler optimizations
+** TODO constant folding
+** TODO simplification pass, dead-code elimination
+   This is important in particular for the output generated by
+   syntax-rules.
+** TODO lambda lift
+   The current closure representation is not very efficient, so this
+   would help a lot.
+** TODO inlining (and disabling primitive inlining)
+   Being able to redefine procedures is important though.
+** TODO unsafe operations
+   Possibly, don't want to make things too complicated or unstable.
+** TODO plugin infrastructure
+** TODO type inference with warning
