Generate lower case ASCII alphabet

Generate lower case ASCII alphabet is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

Generate an array, list, lazy sequence, or even an indexable string of all the lower case ASCII characters, from 'a' to 'z'.

If the standard library contains such sequence, show how to access it, but don't fail to show how to generate a similar sequence. For this basic task use a reliable style of coding, a style fit for a large program, and use strong typing if available.
