[Python-ideas] back-references in comprehensions

[yoch melka]

Hi,

I would like to use backreferences in list comprehensions (or other
comprehensions), such as :

[[elt for elt in lst if elt] for lst in matrix if \{1}]
# \{1} is back-reference to filter result of the
# first comprehension ([elt for elt in lst if elt])

It would be possible to do this ?

Thanks
