 === Case 1 ===
-  The function would work OK with masked arrays if it called {{{ma.asarray}}} instead of {{{numeric.asarray}}} (as it's currently the case). A fix could be to add a {{{mask=False_}}} property by default to any {{{ndarray}}}, and get rid of the {{{MaskedArray}}} class ?

A second possibility would be to check in {{{numeric.asarray}}} whwther the argument is already a (masked) array.
