Maybe it's not needed, but it reads like it does the right thing,
since the
variable gets assigned immediately
Ah, note that these are initialisations, not assignments. This flag
tries to conservatively indicate whether a variable is ever assigned,
i.e., can change its value observably, or is quasi const (which is
relevant for optimisations later). For lexical declarations, which have
a proper TDZ, initialisation does not observably change their value
(though it does for 'var').
