[Haskell-cafe] Query on list comprehension

What are the limitations of list comprehension. I want to use listcomprehension to output the pattern below. So a mixture of a's and newline characters. The part im stuck at is creating arguments in the listcomprehension to stop at some point then execute next loop. Is it even possible to create the pattern below purely from list comprehension.Thankyou in advance. a aa aaa -- View this message in context: http://www.nabble.com/Query-on-list-comprehension-tp22573574p22573574.html Sent from the Haskell - Haskell-Cafe mailing list archive at Nabble.com.
