drop -text -containers
drop n xs returns the suffix of xs after the first n elements, or  if n > length xs:
> drop 6 "Hello World!" == "World!"
> drop 3 [1,2,3,4,5] == [4,5]
> drop 3 [1,2] == 
> drop 3  == 
> drop (-1) [1,2] == [1,2]
> drop 0 [1,2] == [1,2]
It is an instance of the more general Data.List.genericDrop, in which n may be of any integral type.
O(1) drop n xs returns the suffix of xs after the first n elements, or  if n > length xs.
O(n\c)/ drop n xs returns the suffix of xs after the first n elements, or  if n > length xs.
dropWhile p xs returns the suffix remaining after takeWhile p xs:
> dropWhile (< 3) [1,2,3,4,5,1,2,3] == [3,4,5,1,2,3]
> dropWhile (< 9) [1,2,3] == 
> dropWhile (< 0) [1,2,3] == [1,2,3]
Delete the drive, if it exists.
> dropDrive x == snd (splitDrive x)
Remove last extension, and the "." preceding it.
> dropExtension x == fst (splitExtension x)
Drop all extensions
> not $ hasExtension (dropExtensions x)
Drop the filename.
> dropFileName x == fst (splitFileName x)

Remove any trailing path separators
> dropTrailingPathSeparator "file/test/" == "file/test"
> Posix: not (hasTrailingPathSeparator (dropTrailingPathSeparator x)) || isDrive x
> Posix: dropTrailingPathSeparator "/" == "/"
> Windows: dropTrailingPathSeparator "\\" == "\\"
The genericDrop function is an overloaded version of drop, which accepts any Integral value as the number of elements to drop.
Rotates backdrops for X11 displays using Imagemagic.
Traditional buffer-overflow attacks work by filling a data buffer with exploit code and then redirecting execution to that buffer. As a countermeasure, modern operating systems will forbid (by default) the execution of writable memory regions.
Return-oriented programming  is an alternative exploitation strategy that works around this restriction. The exploit payload is built by chaining together short code sequences ("gadgets") which are already present in the exploited program, and thus are allowed to be executed.
dewdrop is a Haskell library for finding useful gadgets in 32- and 64-bit x86 ELF binaries. You can describe the desired gadget properties with a Haskell function, and use the Dewdrop module to make a customized gadget-finder program. Or you can import Dewdrop.Analyze and integrate this functionality into a larger program.

A variety of drop which omits the checks on n so there is an obligation on the programmer to provide a proof that 0 <= n <= length xs.
