	// 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
