Re: [Haskell-cafe] Implicit concatenation in list comprehensions

Except that it's ugly compared to the proposed extension. With the extension you can put things in the same, right place:

renderGhcOptions opts =     ghcOptExtraPre opts

 -- source search path  ++ [ "-i"      | not (null (ghcOptSearchPath opts)) ]  ++ [ "-i", dir | dir <- ghcOptSearchPath opts ]

Following the discussions, I now support this extension too - I keep seeing more and more places in my code where it would be very useful. Thanks Neil
