-version 0.9.x
-=============
-
 - pragmas need 'bindSym' support
 - allow simple read accesses to global variables --> difficult to ensure that
   no data races happen
 - pragmas need re-work: 'push' is dangerous, 'hasPragma' does not work
   reliably with user-defined pragmas
 - memory manager: add a measure of fragmentation
-- implement 'bits' pragmas
 - we need a magic thisModule symbol
 - optimize 'genericReset'; 'newException' leads to code bloat
 
+- prevent 'alloc(TypeWithGCedMemory)'?

 CGEN
 ====
 - codegen should use "NIM_CAST" macro and respect aliasing rules for GCC
