Recently I am writing a self-use package for calculating space differiente. The package accept 1-st order differiente and 2-nd order differiente but throw error when calculating higher oders.
I was thinking about something like types like eval(SpaceDiff{1}, arg...)
and eval(SpaceDiff{2}...) rather than juist 1/2, as it can throw an error
in a separated defination.
But I did not see anything similar in the document. Is there a similar way
to specify types or methods by an actual int?
Thank you
