L
L is the syntactic construct for Haskell-style list comprehensions and lazy list creation. To create a new List, just wrap an interable in L[ ].
List comprehensions can be used with any instance of Enum, including the built-in types int, long (in Python 2), float, and str (a char).
There are four basic list comprehension patterns:
>>> from hask.lang import L
>>> # list from 1 to infinity, counting by ones >>> L[1, ...] L[1, ...]
>>> # list from 1 to infinity, counting by twos >>> L[1, 3, ...] L[1, 3, ...]
>>> # list from 1 to 20 (inclusive), counting by ones >>> L[1, ..., 20] L[1, ..., 20]
>>> # list from 1 to 20 (inclusive), counting by fours >>> L[1, 5, ..., 20] L[1, 5, ..., 20]
