A special form is where the code is not supplied in-line but instead comes
from the =codeDict= dictionary in the =system= directory. It should contain
a =fixedValue10= entry:
#+BEGIN_SRC c++
fixedValue10
{
code
#{
operator==(min(10, 0.1*this->db().time().value()));
#};
}
#+END_SRC
The advantage of using this indirect way is that it supports
runTimeModifiable so any change of the code will be picked up next iteration.
