I (and I believe Alex) object to name declaration *statements* and/or the strong typing of *names*. I (and I believe Alex) approve of the strong typing of *objects*, which must somehow be indicated in the object creation *expression*. This is absolutely fundamental to Python. There are at least three ways to indicate the desired object type: literal type, constuctor (and other function) identity, and constructor (and other function) arguments. When constructor arguments only specifiy the type of members of a homogeneous collection object, the visible type() of the collection itself may not be affected. I believe member type specifications for numerical and num- arrays are like this, as they are for stdlib array.arrays. Sorry, no conflict ;-) Terry J.
