Feature Request: Make list_vars invisibly return a list of vars

[billdenney]

It would be helpful if there were a simple way to get the mapping of column names to parameter type. An interface that seems to be a good fit would be to return the list of vars invisibly from the list_vars() function. (Or to make it return a new object type with a print method that printed like list_vars() currently does.)

Hi @billdenney happy new year and thanks for the suggestion. I will try to implement that in the upcoming 0.5 version of xpose.
