Python has partially the concise syntax you are looking for
A[A>0] += 128
A[1:98:2]
is perfectly valid for numpy arrays, for something like

1:2:97 98 99

I see no syntactic sugar only something like range(1,98,2) + [98, 99], while 
easier subscripting can be done with the colon syntax of course.
As I am not the perfect numpy/scipy coder maybe someone knows better and I am 
wrong here.

Btw I am someone who likes having domain specific languages and not one general 
purpose language to rule them all, that is my reason to use environments like 
octave, scilab, maxima, they just feel more natural, but that is a very 
personal point of view of course.
