If you want to program in Haskell, why don’t you get a job programming in Haskell rather than inventing something so ugly? You would not get through code revie

PS. for a less extreme version, the 1-elem-tuple trick is useful if you need an intermediate variable in a listcomp: [ y+y for x in my_list for y in (foo(x),) ] but it's (obviously) ugly & only useful if you're in a REPL and don't want to rewrite the whole thing.
