Dear All,
I'm still playing around with macros and figured out a way to define a
macro for list comprehension.
The syntax looks like this:
OddSquares = <<list X*X with X <- [1 2 3 4 5 6 7 8] where {IsOdd X}>>
You may use any number of generators. Every generator can be accompanied
by an optional guard.
The generated code basically follows the explanation in CTM, p. 301,
i.e. consists of nested calls to lazy versions of Map and Filter.
You may download the source code here:

Please report bugs and problems.
Enjoy!
Wolfgang
