We explain how the use of twisted variables for the spinors of supersymmetric Yang--Mills theories simplify their construction and allow better proofs of non renormalisation theorems. Then, we show that a twisted superfield formalism can be constructed, even for maximal supersymmetry, for which the constraints can now be solved off-shell, which is a good advance.
