ChapterÂ 16.Â Using Parsec
The task of parsing a file, or data of various types, is a common one for programmers. We already learned about Haskell's support for regular expressions back in the section called â€œRegular expressions in Haskellâ€. Regular expressions are nice for many tasks, but they rapidly become unwieldy, or cannot be used at all, when dealing with a complex data format. For instance, we cannot use regular exp

Recent experiences from a few of my fellow C++/Java programmers indicate that they read various Haskell tutorials with "exponential speedup" (think about how TCP/IP session starts up).
