some package:parsers
Usually, someSpace consists of
one or more occurrences of a
space. Some parsers may choose to recognize line comments or
block (multi line) comments as white space as well.
skipSome p applies the parser p one or more
times, skipping its result. (aka skipMany1 in parsec)
Use this to easily build the definition of whiteSpace for your
MonadParser given a comment style and an underlying someWhiteSpace
parser
