Surely it could equally mean: fully expand the right-hand side
immediately, append to the left-hand variable, preserving its type if
set, else making it immediate.  Then, if it was previously
deferred-evaluation, its prior value remains deferred-evaluated - only
the part appended is evaluated right away.
