Right now I see a problem with Expr (lval), when the C function
expects an pointer (rval). This should be handled at least for
variables, i.e. Expr should include an hint on whether it *is* an
lval. When you produce C code, your data types already should match
the C definitions, else another transformation may be required for
passing parameters back and forth. All that should be built into Expr,
or a DataType member of Expr.
