Corrections to the Parsec library introduction

[adql]

For some reason, the introduction to the Parsec library has some operators missing (namely <$>, <*> and <|>) beginning with the two flavors section. This makes it hard to follow, especially for a newcomer not yet familiar with Applicative.

Also, the result to test expressionParser "(123+(324-456))" has all the T* data types appear as J*: Right (JNode (JTerminal 123) JAdd (JNode (JTerminal 324) JSubtract (JTerminal 456))).

Since that post is featured as a tutorial in the Parsec readme,¹ I thought it should be corrected. I already have it prepared and can submit a pull request, I only wanted to raise it here first since it's your personal blog.

Thanks for that helpful tutorial!

Thanks for the heads-up and the correction! I’m happy to merge the fix! I’ll be out for the next 10 days but can take a look after that :)
