alt Hacker News"try and <clause>" is syntactically correct.
That is to say,
> I'm going to try and change the course of Hip-Hop.
can be parsed as
> I'm going to try; I'm going to change the course of Hip-Hop.
which has been subject to a well-understood extraposition process to factor out the leading "I'm going to" from all the clauses, so that a single copy of it distributes into all of them.
It's essentially the same as what is going on in the following unassailably correct sentence:
> I'm going to turn on the TV, crack open a beer, and watch the game".
Also note that this "and" is not something which exclusively pairs with "try":
> Linguists, go ahead and fight me!
There's explanations in the article of why 'try and' can't be parsed as simply as that kind of parallel ellipsis structure.
No reordering: You can't rephrase as I'm going to change the course of Hip-Hop and try the way you can I'm going to watch the game and crack open a beer
No use of both: You can't say I'm going to both try and change the course of Hip-Hop the way you could I'm going to both crack open a beer and watch the game
No inflections: You can't say I have tried and changed the course of Hip-Hop the way you can I have cracked open a beer and watched the game
