-> for gnu classpath absolutely necessary
-> estimated effort: unknown
+(l) replace signals with "nice traps"?
+ pro -> don't rely on operating system anymore
+ pro -> maybe better ghci behaviour?
+ cons -> at some point, signals are useful for debugging?
+ cons -> better "template" tricks are needed, as we cannot insert more
+ instructions or want to place nop's at production code path
+
(l) gnu classpath integration
-> would be awwwesome
-> depends on: exceptions, jni (?)
(l) check different types (byte, long, ...)
+(l) get rid of CUInt where appropriate
+ -> CPtrdiff and CSize (ptrdiff_t and size_t) is more portable
+
(l) floating point support
(h) better code generation
