20331 A MIPVariable's repr should include some useful information Matthias Köppe "{{{

I think the print method should instead of ""dimension 1"" (which apparently means tensor order 1, rather than dimension 1 -- see #17643) print some useful information, such as the name of the variable and the dimension (number of components).
