System dimensions
Dimensions necessary for the proper behaviour of the system should not be allowed to be manipulated. That includes deletion. Should we write the TransLucid interpreter in TransLucid, we will reconsider this decision. This will allow rewriting, optimization and specialization of the interpreter as in Smalltalk.

That makes sense, it’s fairly trivial to do too. Although we should define semantics better, currently it is just in the c++ interface that dimensions can be deleted. It would be better if it was all consistent with time and so on and could actually be done with in TransLucid too.

Just to confirm the email exchange, system dimensions will be put in a separate symbol table in the parser so that way they have a container which has a list of all their names, accessible to the programmer.

Yes that is what I will do.

I have completed this now, the interface is the same. System dimensions are in system_dimension_symbols, so addDimensionSymbol and removeDimensionSymbol only affects user dimensions.
