If it were allowed then you could do nasty things like storing the 
address of a local variable in a field, and when the local's stack frame 
is destroyed there'd be a dangling pointer.

It depends on what exactly you're trying to do. Why do you need to store 
a managed pointer in a field?

If you're willing to sacrifice verifiability of your code, you can 
forcibly convert the managed pointer to a native int ('conv.i') and 
store that in a field. (Be careful of making the garbage collector angry
