* Separate symbols from variables to avoid shape problemsNao Pross2024-06-0411-163/+144
| | | | | | | | | Variables are now expression that have a shape and contain a symbol. The symbol in its own is not a variable, as the shape is unknown, but this information can is stored in the state object. So it is possible to reconstruct a variable by doing init_variable_expr(sym, state.get_shape(sym))
