         IL_0002:  initobj X
 
 Interestingly, the IL encoding used by nemerle is actually shorter
 than the one mcs uses. Am suprised that this is the case. Today, the
 initobj version is probably much faster speed-wise (it is inlined...)
 however.

+I guess you refer to our
+   newobj instance void valuetype thistest/xxx::.ctor()
+
+but this is just a consequence of declaring explicit parameterless
+ctor in struct (which is forbidden in C#). Without this ctor we emit
+the same 
+IL.
+
+We will discuss the issue of definite assignment and parameterless
+ctor (that is I'm not sure we would like to follow C#'s design). So,
+IMHO this is a runtime bug, especially that code verifies fine. If
+there is something in CLR spec, which forbids such code, please tell me.
