should be just store 5->*foo; add foo,1->foo
the dereference does the post-inc. needs to be delayed somehow. could build a list of post-inc terms after the current expression, but might be really messy.

If arraysize>0, its an array and requires array notation
If arraysize<0, its an array with undefined size - GetDef will fail if its not already allocated.

If allocate is 0, will only get the def

If allocate is 2, a new def will be allocated, and it'll error if there's a dupe with scope (for ensuring that arguments are created properly)
