  • Ticket #24176 – Description

    initial v12  
    1 In order to be able to express solution sets from !SymPy's `solveset` a set comprehension constructor as equivalent to !SymPy's imageset is needed. As the arguments are symbolic the most natural way to do this would be a formal symbolic function named like `set_of_all` taking a term argument and a list argument containing `element_of(...)` function expressions.
     1In order to be able to express solution sets from !SymPy's `solveset` a set comprehension constructor as equivalent to !SymPy's `imageset` / `ConditionSet` is needed. As the arguments are symbolic the most natural way to do this would be a formal symbolic function named like `set_of_all` taking a term argument and a list argument containing `element_of(...)` function expressions.
