If you hold on to a large data structure in garbage collected (GC) memory

for relatively longer times it puts undue pressure on GC, unnecessarily

increasing the work done by GC and also increasing the duration of GC

pauses. A `CompactList` allows you to keep a large list in a Compact Region

not touched by GC, thus avoiding any GC overhead.  This is essentially like

a convenient in-memory append only file where you can write a list of

Haskell values without having to marshall or serialize them.
