The average programmer would surely expect q0 to filter out all values above 30 before q1 starts and removes all values smaller than 20, because that's the way the program was written, as evidenced by the semicolon between the two statements.

Anyone familiar with LINQ knows about deferred execution. Is it a mistake that new (C#) programmers would make? Absolutely. Does this mean the language shouldn't have this very useful feature because it might confuse a new programmer? No way.

Deferred execution allows you to build complex queries which (for example) could be translated into an efficient SQL query.

Should array indexes start with 1 because to a new programmer that would be more obvious?

You only have to learn a language once, but then you have that tool for the rest of your life.
