I think such compatibility, IMHO, is quite useless. What can we do with
a half-baked assign operator? I dont see much returns for actually going
 and implementing such a feature. Who knows, this maybe a side-effect
of the Matlab-parser.

I must admit I dont understand semantics of how cs-lists, or lists are
supposed to be used.
