No I don't need a loop if I don't use the listcomp. I could say
a = map(lambda x,y: f(x)+g(y), ifilter(lambda x,y: h(x,y).frob==7,
the listcomp is basically syntax sugar for that.
The issue here is that Python is simply more expressive than C++,
which doesn't support creation of higher order functions like that.
However, one of the consequences of programming in this style is
you allocate a lot of temporary objects which best managed by GC.
