// As a consequence of the DA/DU rules in the JLS (draft of
// forthcoming 2e), all variables are both definitely assigned

// correctly suppresses DA/DU-related errors in such code.
// The use of the DA status of the 'this' variable for the extra
// check below on correct constructor usage, however, does not quite
// fit into this DA/DU scheme. The current representation of
// Vsets for unreachable dead-ends, does not allow 'clearVar'
// to work, as the DA/DU bits (all on) are implicitly represented
// by the fact that the Vset is a dead-end. The DA/DU status
// of the 'this' variable is supposed to be temporarily
// cleared at the beginning of a constructor and during the
// checking of constructor arguments (see below in this method).
// Since 'clearVar' has no effect on dead-ends, we may
// find the 'this' variable in an erroneously definitely-assigned state.
// As a workaround, we suppress the following error message when
// the Vset is a dead-end, i.e., when we are in unreachable code.
// Unfortunately, the special-case treatment of reachability for
// if-then and if-then-else allows unreachable code in some circumstances,
// thus it is possible that no error message will be emitted at all.
// While this behavior is strictly incorrect (thus we call this a
// workaround), the problematic code is indeed unreachable and will
// not be executed. In fact, it will be entirely omitted from the
// translated program, and can cause no harm at runtime. A correct
// solution would require modifying the representation of the DA/DU
// analysis to use finite Vsets only, restricting the universe
// of variables about which assertions are made (even in unreachable
// code) to variables that are actually in scope. Alternatively, the
// Vset extension and the dead-end marker (currently a reserved value
// of the extension) could be represented orthogonally. In either case,
// 'clearVar' could then be made to work on (non-canonical) dead ends.
