This idea already appeared few times. I proposed to introduce a flag (e.g.
-OOO) to ignore function and variable annotations in compile.c
It was decide to postpone this, but maybe we can get back to this idea.

In 3.6, typing is already (quite heavily) optimized for both speed and
space.
I remember doing an experiment comparing a memory footprint with and
without annotations, the difference was few percent.
Do you have such comparison (with and without annotations) for your app?
It would be nice to have a realistic number to estimate what would the
additional optimization flag save.
