increases complexity -- wrong -- I only replaced the matching types -- the
using code was not modified.
The number of lines for the wrapper are minimal -- I only implemented the
methods I'm using.
I don't care about complexity the compiler has to manage.
I care about the complexity I have to manage.
I could introduce some filtering to avoid storing identical instances which
would even more decrease the memory foot print.
