Succeeds if and only if we are at the end of input.

asTypeOf is a type-restricted version of const. It is usually used as an infix operator, and its typing forces its first argument (which is usually overloaded) to have the same type as the second.

This function is somewhat compatible with Win32's TimeGetTime()

The isSubsequenceOf function takes two lists and returns True if all the elements of the first list occur, in order, in the second. The elements do not have to occur consecutively. isSubsequenceOf x y is equivalent to x `elem` (subsequences y). Note: isSubsequenceOf is often used in infix form.

Examples

>>> "GHC" `isSubsequenceOf` "The Glorious Haskell Compiler"
True

>>> ['a','d'..'z'] `isSubsequenceOf` ['a'..'z']
True

>>> [1..10] `isSubsequenceOf` [10,9..0]
False

For the result to be True, the first list must be finite; for the result to be False, the second list must be finite:

>>> [0,2..10] `isSubsequenceOf` [0..]
True

>>> [0..] `isSubsequenceOf` [0,2..10]
False

>>> [0,2..] `isSubsequenceOf` [0..]
