This limitation is described at URL:

at the section "Macro containing a class definition"

We are hoping to remove this limitation, but this is non-trivial.
The implementation is highly compiler dependent.
This limitation is not very important in the data analysis stage,
but prevents the use of the interpreter in the code development phase.
