But this is already documented feature, and it works as intended, so
moving it into something like "myObject._size" will bring backward
incompatibility and break all FuncDesigner user API and style, where
no underlines are present, it will seem like a hack that it really
is.

Sometimes apriory knowing size value as fixed integer brings some code
speedup, also, if a user supplies the value, a check for computed
value wrt the provided size is performed each time.
